2.1 DOCUMENTATION AND DATA ANALYSIS
2.1.1 ABSTARCT
Our prime goal was to bioprospect macrofungi on the basis of the ethno-myco-
medicinal traditional knowledge. Due-diligence in terms of the location, have an
idea about the quantum of diversity available and ensure ethnomedicinal
background to get valid practices. Due to lack of any documented investigations
we had to go for a theoretical estimation of possible size of diversity since the
dense forest area is very low. According to our liberal and conservative estimates
there may be 3000 or 1100 to 440 species of macrofungi, respectively in Gujarat.
Substantial sum of these could be unique to this location. We locked on the
Dangs, as it has the maximum very dense forest with maximum cover. Moreover
the tribes of this location were found to be well known for their traditional
etnomidicinal knowledge. In order to test and validate the hypothesis that the
Dangs was an appropriate location a positive control location with opposite
climate and geography was considered as well.
2.1.2 INTRODUCTION (Gujarat:an overview)
On 5/1/1960 Gujarat was established as a state, after being separated from
northern state and Maharashtra in south. It covers the Western part of India and is
surrounded by Pakistan and Rajasthan in the north, Madhya Pradesh in the east,
Maharashtra in the South-East and Arabian Sea in the West. The 1600 km
coastline of Gujarat is 1/3rd of the nation’s coastline and thus is the longest
amongst all the states. Almost 79.8% of 50,671,017 people inhabiting in 1,96,024
sq km of Gujarat are literate. It
witnesses an average rainfall of
93.2 cm and has max-min
temperature of 25-45oC and 15-
35oC in the summers and
winters respectively

E, the state enshrines various ecosystems like grasslands, dry and wet deciduous
forests, deserts, scrublands, wetlands, mangroves, coral reefs, estuaries and
gulfs, harboring many rare and endangered species. The state gets rainfall
around 300mm in the north, which is not as scanty in the southern provinces
receiving 2500 mm. The land is divided in to three regions namely Gujarat
Mainland, guarded by mountains like Aravalli, Satpura, Vindhya and Sahyadri.
Secondly, the famous rann of Kutch and finally the Saurashtra peninsula. It
withholds several National Parks, including Gir Forest National Park (Girnar), near
Junagadh, Velavadar National Park in Bhavnagar District, Vandsa National Park
in Bulser District, and Marine National Park by the Gulf of Kutch in Jamnagar
District. There are also a number of wildlife sanctuaries and nature preserves,
including Anjal, Balaram-Ambaji, Barda, Jambughoda, Jessore, Kachchh-desert,
Khavda, Nal-sarovar, Narayan-sarovar, Paniya, Purna, Rampura, Ratanmahal,
and Schoolpaneshwar (gujaratindia.com). Geographic genesis of the state is said
to be marked by the breaking of western continental margin from the Gondwanan
land due to the northward drift.
Gujarat has a total forest cover of 14,946 sq km, of which 114 sq km is very
dense forest, 6,231 sq km is moderate dense forest and 8,601 sq km is open
forest (Fig 2.1.1). According to a 2004 report of Forest survey of India the forest
cover has decreased from 9.8% (Dir. of Econ. and Stat., Govt. of Gujarat, 1995) to
9.6% that surmounts to a total loss of 13% forest cover in 2 years due to human
activities (gisdevelopment.net). Thus loss of habitat would lead to loss of diversity
and disappearance or dilution of traditional knowledge.
2.1.3 Due-diligence study step 1: Identifying the region of research
Of the total number of plants documented from Gujarat, around 353 species occur
in desert zone, 540 in semi-arid zone and 488 in Malabar zone (Gavali and
Sharma, 2004). The dense forest cover in Gujarat is now limited to just three of
the 26 districts, Dangs (78 sq km), Surat (27 sq km) and Junagadh (9 sq km)
(fsi.nic.in). Hence, it was estimated that the Dangs enshrine almost 68.42% of the
states very dense forest cover. Thus this region had to be the prime location of
our research as it being in the Malabar-western Ghat hill zone had better forest

cover and comparable diversity both of which are necessary for more number of
fungi per plant.
To test the hypothesis that the traditional knowledge and macrofungal
biodiversity and ethnomedicinal diversity in the Dangs will be more or better we
took a positive control area. This was Jessore sloth bear sanctuary, which was
opposite to the Dangs in every sense. It is situated in the North at the opposite
extreme of the Dang and had arid climate with scanty rainfall. Further down the
line, comparison regarding the quantity and quality of traditional knowledge and its
related macrofungal diversity, in between both the communities is done. The
details of both the regions are elaborated below.
2.1.3.1 Jessore community
This community was defined as the sum of those local people inhabiting in and
around the Jessore sloth bear sanctuary (Fig 2.1.2A, 2.1.3 A & B, 2.1.4 A). This
sanctuary is located in the Aravalli hill range in North Gujarat next to the
Rajasthan and harbors, Southern dry mixed deciduous and desert thorn types of
forests. Jessore is the second highest hill of Gujarat. The major floral species
comprise Ber, gando baval, khair, Isaraily baval, dhav, dudhalo, gando baval,
dhavado, saledi, kadaya, siras, gorad etc.
The flagship specie of the area is Sloth bear. The top carnivore, leopard
cohabits the area with other vertebrates. Other important animals include rhesus
macaque, Indian civet cat, Indian porcupine, striped hyena, fox, jackal, bluebull,
wild boar, hare, langur, wolf etc. The reptiles include snakes, tortoises and lizards.
The avifauna includes spurfowls, cuckoos, barbets, woodpeckers, tree pies,
flycatchers, shrikes, spoonbills, storks, cranes, egrets and many raptors.
Prosopis invasion occurring almost in pure composition in certain areas
needs phased replacement with the local floral species. The area being drought
prone, water conservation works need special attention for improvement in
hydrological cycle of the area.

There are different communities such as 'Thakore', 'Chauhan', 'Koli',
'Kumbhar', 'Mali', 'Rabari', 'Harijan', 'Waghari' and 'Agrawals' in the villages
located near the Sanctuary. The tribal communities of the area are 'Majirana',
'Garasia', 'Gamar' , 'Damor' , 'Khokharia' , 'Dama', 'Dhajora', 'Dhrangi', 'V ansia'
and' Kharadi': Traditionally the people are religiously inclined. Economy of the
people is mainly agrarian. Most of the people are engaged in agriculture. Cattle-
rearing is the other major occupation of the villagers as well as of 'Rabaris'. The
people depend upon forests for fuel-wood, fodder, grazing, and collection of
honey, 'timru' leaves, gums, wild fruits and medicinal constituents of plants. Honey
collection, grazing, lopping practices and fire wood collection are the major
damaging factors, adversely influencing the habitat. Nilgai (Blue bull) invades the
croplands and cause damage to the farmers (gujaratforest.gov.in).
2.1.3.2 Purna community
This community was defined as the sum of those local people inhabiting in and
around the Purna wildlife sanctuary (Fig 2.1.2B, 2.1.3 C & D, 2.1.4 B & C). This
sanctuary is located in the Dangs. It has the thickest forest cover in the Gujarat.
Apart from tall teak trees, other floral species are sadad, timru, bamboos, khair,
kalam, haldu, sisham (rosewood), salai, kadaya, killai, sevan, tanachh etc.
Moreover Bamboo is wide spread and for habitat for specific mushrooms.
The sanctuary area of 160.8 sq. km. is spread over a hilly terrain with
plateaus and small valleys. These hill ranges are the western and northern
extreme of the Western Ghats. The landscape of sanctuary is traversed by river
Purna and Gira along with other and rivulets. It receives moderate to even heavy
rainfalls that averages to around 250 cm annually, which is the highest. The forest
is typically a tropical moist deciduous type. The landscape is lush green, thick
forests, interspersed with rivers, small tribal villages and scattered fields. The
human population is totally tribal represented by Bhils, Warlis, Konkanas, Dubdas,
and Kolchas etc. The forests support a rich tribal culture in the form of houses,
dresses, jewelry, agriculture, fishing, musical instruments and folk dances
(gujaratforest.gov.in).

The forests of Gujarat are said to be biodiversity rich withholding 13% of
countries plant diversity. Moreover, 15% of 29 tribes nurture traditional knowledge
encompassing 750 medicinal plants. The Tribal population in Gujarat is mainly
concentrated in the eight districts along the Eastern border of the state. 96% live
in the Dangs, Valsad, Surat, Bharuch, Vadodara, Panchmahals, Sabarkantha and
Banaskantha. The tribal region extends from Sabarkantha district through
Panchmahals down to Surat, Valsad and the Dangs. About 92% of the scheduled
tribes are from the rural areas (Patel, 2005).

2.1.4 Due-diligence study step 2: Identifying tribes with rich traditional
knowledge
As such the Dangs are populated with other tribes like Kunbi and Gamit. The
Kunbhi are said known to be farmers across central and western India. We found
even a mushroom named after them as “Kunbhi kunwar” meaning a farmer’s
prince as it grows in farm borders. Later during the rule of Gond tribe, the
Deshmukhs and Despandias were administrators. One of the Deshmukh
participated in our program and had made significant contribution of
mycoethnomedicine in this region. Deshmuks were considered as leading
kunbhis. The Gamit community is one among the major tribes in Gujarat and are
located in various parts of Gujarat like the Dangs, Valsad, Surat and Bharuch
(indianetzone.com). Gamit means a village dweller and are hard-working people.
Enthoven, a British anthropologist, commented that these people resemble proto-
Australoids and had entered the country 50,000 to 60,000 years back. This
community specifically has earned a name for deep knowledge of ethnomedicine.
They are popular and well known because of its unique mode of treatment. This
community has survived the test of time by passing its knowledge to the next
generation, which may have been diluted lately due to deforestation, afforestation,
climate change or migration of tribes towards urban localities.
Around 15% of total state population is tribal that spread across the forests
and the eastern boundary of the state, and have rich traditional knowledge.
Changing life style, market influence and urban migration are diluting out
traditional knowledge.
2.1.5 Due-diligence study step 3: The estimate of probable species diversity
Approximately 9.6% of the forests of Gujarat have managed to harbor mystic
ranges of fungal biodiversity. Our prime interest resides in the macro-fungi
belonging to Basidiomycotina and Ascomycotina, more commonly known as
mushrooms. Out of a huge number of total estimated species of fungi world wide
only 5% (69,000 to 74,000) are known, out of which only 10,000 are known to be
the fleshy macro fungi and only a handful of these are known to be lethal.
As reported by “Gujarat Ecological Commission” (GEC), 164 fungi out of
23,000 in India were estimated to be in Gujarat. Apart from this, according to the
2.1 Due-diligence study for location and species diversity 29
DOCUMENTATION & DATA ANALYSIS
Chapter-2
study conducted in Jessor, by Gujarat Ecological Education Foundation, the total
number of plant species reported was 400, of which only two were fungi. Wide
varieties of mushrooms are reported from various parts of Gujarat. The tribes in
Dang and all over Gujarat are engaged in gastronomical and medicinal practices
of mushrooms. But there was no proper systematic documentation regarding the
biodiversity of species and ethno-myco-medicinal traditional knowledge.
2.1.5.1 MATERIALS AND METHODS
For calculation of probable species diversity conservative (Mueller et al., 2007)
and liberal (Sankaran, 2003; Hawksworth, 2001) vascular or angiosperm plant to
fungi ratio were employed. The final datasheet was formulated from the well-
known data sheets as, Data sheet of European council of fungi (ECCF), Data
sheet of Biodiversity of fungi (Mueller and Bills, 2004), Data sheet of Rajasthan
University; department of Botany, Data sheet of Madras University; Center for
Advanced Study in Botany and Data sheet of British Mycological Society. We
collected such information and identified the mushrooms up to genus level by their
morphological and anatomical characters (Singer, 1975; Leelavathy, 2000). Data
sheets prepared for exhaustive documentation, were bifurcated as macrofungal
documentation containing its field (Annexure 1) and morphological data and
know-how documentation containing data about the traditional uses of
mushrooms (detailed in chapter 2.2 and 2.3). The colloquial names, as “Vansarta”
(if growing on bamboo), “Kulambhi-kunwar” on soil, and puffballs for “bhupidh”,
coined by the native people are used here for tagging an unidentified species.
2.1.5.2 RESULT AND DISCUSSION
After Insects, fungi withhold the second largest biodiversity. The huge figure of
total estimated species of fungi is 1.5 million (Chang, 1993; Sankaran, 2003;
Hawksworth, 2001). Out of which 74,000 are known that stands around 5%. Out
of this 74,000, only 10,000 are known to be the fleshy macro fungi. This ratio of
number of mushroom from known number of fungi stands to be around 14%. But
the paucity of data is reflected by very few records of mushrooms in Gujarat. Only
a handful are known to be lethal, as 2000 species from 30 genera are known to
be edible, But only 80 of them are grown experimentally, 40 cultivated

economically, 22 commercially and only 6-8 are produced at industrial scale
(Chang, 1993). In case of mushrooms only 10% of them are known, of which 5%
are rendered useful on utilitarian grounds, vacating a large room to be
accommodated and delved for various applications regarding those yet to be
identified (Hawksworth, 2001). Of 14,000 species reported globally, India
harnesses a prolific fraction of 1200 (8.5%) species of mushrooms, seemingly the
tip of the iceberg (Natrajan, 2005). Ascomycetes are estimated to constitute 40 to
45% of the total Indian fungal population. As such basidiomycetes have received
primary attention since several decades. An estimate extrapolates 10,000
basidiomycetes species within the overall fungal estimates of 1.5 million
(Manoharachary et al., 2005). Mushrooms alone are represented by about 41,000
species, of which approximately 850 species are recorded from India. Of these
round about 60 wild mushrooms, representing 54 species in 36 genera were
recorded around Mumbai that is very close to southern Gujarat (Deshmukh,
2004). Extensive mushroom species collections and surveys were undertaken
extensively in regions like Himalayan region, Punjab, Kerala and Western Ghats.
A paper reports 300 species of mushrooms and toadstools of which nearly 72
species distributed in 15 fungal genera were formed mycorrhiza with Abies
pindrow Royle, Betula utilis D.Don, Cedrus deodara (Roxb.) Loud, Picea
smithiana (Wall.) Boiss, Pinus roxburghii Sarg, Pinus wallichiana A.B. Jackson,
Rhododendron arboreum Smith, Quercus incana Roxb. and Quercus
semicarpifolia Smith. As many as 24 fungal species were found to be associated
with Q. incana alone (Manoharachary et al., 2005).
Of all newly describe fungi during 1981-2000, 60% were discovered from
tropics. Out of this India tops the list with 900 species documented in past 10
years (Sankaran, 2003). In India, 6900 species of fungi are known out of the total
74,000 known species that are found in the world. Thus 9% of fungal biodiversity
is India’s contribution to the world.
2.1.5.2.1 The liberal theoretical estimate of Species diversity
Fungi are known to occur by ratio of 1:10 on plants (Sankaran, 2003;
Hawksworth, 2001). According to which, the total number of species of fungi in
India should be around a ballpark figure of 1,70,000, which is relative to the
2.1 Due-diligence study for location and species diversity 31
DOCUMENTATION & DATA ANALYSIS
Chapter-2
17,000 species of known angiosperms in India. Thus until now only 4.06% of them
(6,900 known out of 1,70,000 theoretically estimated) are reported in India
(Sankaran, 2003). We had calculated above that 14% of known fungi were found
to be mushrooms. So if we abide by this ratio as canon in order to grossly
estimate the quantum of possible mushrooms, then India may withhold around
24,000 of them.
Apart from this, as reported by GUJARAT ECOLOGICAL COMMISSION
(GEC, 1996); in Gujarat total number of fungi estimated was 164, of 24,000 said
to be in India. This barely matches the theoretical estimate of 1,70,000 possible
fungi in India. To estimate the possible number of fungi in Gujarat we have to
know about the number of angiosperms or vascular plants in Gujarat. The
number of angiosperms found in Gujarat is around 2,200 (GEC, 1996). Thus the
number of fungi may be extrapolated to 22,000 species, by the ratio (Sankaran,
2003) of 1:10, in Gujarat. Using the same yardstick of 14% in case of mushrooms
we can say that the number of mushroom in Gujarat could be around “3000”. This
seems to be a mammoth number. Even if we consider a round figure of about 200
species (instead of 164) of fungi identified from Gujarat, the quantum of those
identified, will pigmy to less than 1% of possible 22,000 species of fungi. The state
lacks an impetus in direction of entire fungal biodiversity inventorying and
evaluation due to lesser number of fungal taxonomist and devoted departments
working on it. But if done Gujarat can hit the gold mine hopefully before most of
the endangered ones go extinct. The actual number or fungi or mushrooms in
specific can be more as soil, insect and aquatic borne species are not considered.
Moreover, this may also fall short of estimated numbers due to habitat loss and
climate changes.
2.1.5.2.2 The conservative theoretical estimate of species diversity
A study on flowering plant and macrofungi ratio revealed 21,679 known and
35,000 unknown macrofungal species of which 50% of the known species were
from North America and Western Europe (Mueller et al., 2007). Around 37% of
temperate Asia and 72% of Australasian species were unique. Now 10,000 and
6,827 macrofungal species were found amidst 20,000 and 12,500 flowering plant
species for North America and Europe, respectively. This gave ratio of 2:1 for
2.1 Due-diligence study for location and species diversity 32
DOCUMENTATION & DATA ANALYSIS
Chapter-2
flowering plant over macrofungi species. The ratio produces very high diversity
estimates for macrofungi 85,000-110,000 in totality. This figure became more
realistic (53,000–65,000) when two different plant/macrofungus ratios were
employed, wherein 2:1 was used for temperate regions and 5:1 for tropical
regions. Then the calculations were close to the projected diversity for macrofungi
of 140,000 species postulated by Hawksworth (2001). Assuming that the 21,679
species names that we compiled during this study is an accurate indicator of the
number of ‘‘known’’ macrofungi, 16-41% of macrofungi have been described to
date. Using the 5:1 ratio also generates a realistic figure of macrofungal diversity
for Hawaii (Hemmes and Desjardin 2002). Similarly the 2:1 ratio for temperate
regions yields a prediction of 8,000 species that is close to the 9,000 macrofungal
species estimate in Australasia. This gives a prediction of 3,000 macrofungi for
temperate South America that is 2/3rd of those documented. These estimates are
in line with consistent with a hypothesis of high overall fungal species diversity, of
which macrofungi is 10% (Rossman, 1994). According to this estimate from
53,000–110,000 species of macrofungi, 530,000– 1.1 million species of fungi can
be extrapolated (Mueller et al., 2007).
On this basis the 2:1 and 5:1 ratio, 2,200 species of flowering plants would
emulate 1,100 and 440 species of macrofungi respectively in the state of Gujarat.
And the total species of fungi of which macrofungi is 10% delivers the figure of
11,000 to 4,400 probable species of fungi. These figures, which are for temperate
and tropical regions, are not aligned with the fact that Gujarat is arid Northwards
and semi-arid Southwards climatically. Thus being arid prone Gujarat might have
lesser than 770 average macrofungal species. If 40 to 70 % of these fungi are
unique then around 407-792 to 163-317 macrofungal species can be unique to
Gujarat. If the lower most and highest are considered in round figures then there
may be 160 to 800 unique species in Gujarat.
If these extrapolations are done on 17,000 species of angiosperms known
to exist in India then a considerable chunk is yet to be unearthed. Based on
national estimates it can be said that 3,400 species of macrofungi may be present
assuming India to be tropical. But the estimate would be around 8,500 if the
temperate region ratio is used. An average of both lands up at 5950 which if
rounded off would be around 6000 species of macrofungi. This would escalate to
2.1 Due-diligence study for location and species diversity 33
DOCUMENTATION & DATA ANALYSIS
Chapter-2
60,000 species of fungi based on 10% macrofungi principle (Rossman, 1994). Of
these 2,220 to 4,320 species of macrofungi can be expected to be unique to India.
Gujarat can be estimated to harbor around 13% of national macrofungal diversity.
Most of the macrofungi recorded from India are basidiomycetous. Though
around 65% of the known basidiomycetes of the world are documented in India
there is a huge dearth of ethnomycological data regarding all these species. Of all
the ethnomycological data available only a miniscule of data regarding medicinal
use of these species is registered. Above all, possible existence of 160 to 800
unique species in Gujarat can foretell for sure substantial amount of unique
ethnopharmacological interactions. This in turn implies that there can be brighter
prospects for drug discovery. In other words these regions which have unique
species may have unique metabolites as well and this widens the horizon for the
discovery of multiple novel therapeutic products.
2.1.5.3 CONCLUSION
Thus in a 3 step due-diligence analysis few things were decided. The location of
research was to be the Dangs as it had most of the states dense forest cover and
had harbored tribes with rich ethnomedicinal traditional knowledge. Moreover the
substantial macrofungal species diversity was theoretically substantial and as the
Dangs had better forest types the greater macrofungal diversity was assured.
Moreover a substantial amount of species were to be unique and thus
anthropological interactions with them could have credentials for better
biopropspecting. Finally to test and validate all of these assumptions another
location with opposite climate, geography, scarcer forest, less diverse plantations
was selected. There were no assumptions made regarding the ethnomedicinal
traditional knowledge of Jessor sanctuary. But the effect of the available species
diversity on diversity and depth of traditional medicinal knowledge was seriously
considered. Penultimately after the comparison of the traditional ethno-myco-
medicinal practices from Purna community in the Dangs and the Jessor
community in the Banaskantha, the best ones would be studied further for
pharmacological and phytochemical screening.

2.2.1 ABSTRACT
Traditional ethno-mycomedicinal practices involving macrofungi were documented
using questionnaires from Jessore and Purna communities located in the
Northern and Southern Gujarat. The quality of traditional knowledge within and in
between the communities was compared by informant’s consensus index factor
calculated for each ailment. The possibility of any relation between the traditional
practices and informant’s consensus index factors was assessed as well.
Alternately in order to classify the types of species usages, binary scores were
allotted based on the presence or absence of species storage for later use, open
sharing and specificity of the practices. Followed by this species scores were
subjected to Euclidean distance dissimilarity matrix based hierarchical
agglomerative clustering.
In totality, 23 species were documented addressing various ailments, of
which 9 species were used to treat general aspects like convalescence, whereas
others (14 species) were used for specific ailments. In the Jessore community, 5
of the 7 ailments (71.2%) were related to skin problems, whereas in Purna
community only 7 of 18 ailments (38.9%) had similar usage. The total ailments
addressed and species documented from the Purna community had a greater
diversity and bore higher informant’s consensus index value in comparison to the
Jessore community. Cause and effect of some abnormal informant’s consensus
values, rendering it dubious, are also discussed. Hierarchical agglomerative
clustering revealed the influence of all the three aspects scored as above. The
corner-stone species are more important than other species because they are
necessary for the survival of the traditional know-how and well being of the
communities engaging them and have applications. Moreover, depletion due to
rampant use of such species calls upon there identification and conservation. This
could be achieved to an extent by simple binary scores based clustering. Certain
corner-stone species with closed (absence of) knowledge sharing were found to
withhold specific practices. Those with general medicinal applications can be
useful as nutraceuticals, whereas those with specific claims can be screened
further in order to identify pharmaceutical potentials. In addition to this the present

work mentions the documentation of traditional ethno-myco-medicinal practices of
several species for the first time ever.
2.2.2 INTRODUCTION
The pre-recorded and existing anthropological interaction with macrofungal
biodiversity on the medicinal axis calls for bioprospecting, which is yet to meet its
zenith. Medicinal and edible uses of macrofungi in India is quiet prevalent, some
of which dates back to 1700-1100 BC (Wasson, 1967). Based on plant-fungi
associations (Hawksworth, 2001), theoretical estimates revealed that the state of
Gujarat may possibly harbour around 2000 such species (Lahiri et al., 2008).
Evolving from some of the seminal studies on the cultural significance of the
mushrooms (Garibay-Orijel et al., 2007; Pieroni, 2001), the present work
emphasizes on the species as the centre of study rather than the community
withholding the traditional ethno-myco-medicinal practices (TEMPS). Preservation
of the knowledge pool, identification, conservation and characterization of the
species are the primary factors that necessitated such a paradigm shift facilitating
species-centric anthropological interaction. The communities studied reside miles
away from modern day state-of-the-art medical facilities and depend largely on
traditional and natural medicinal resources, in absence of which or during
emergency they walk down several miles to the nearest city, with high fever for
diagnosis and treatment. Apart from studying the medical practices (entailing
macrofungi) of the communities, pharmacological validation of the claims was also
desired to be followed by. In order to do so, from the pool of practices important
ones were to be identified for further analysis. Thus the present study is an effort
to synchronize the analysis of traditional practices and bioprospect them as well.
The concept of key-stone species is well-known in ecology, wherein such species
are important for the survival of other dependent species. Similarly, vital
macrofungal species that are used to tackle important or critical ailments suffered
by the subjects of a community can be called as corner-stone species.
Identification of such corner-stone species was a prioritized as it was integral to
both ethnomycological and bioprospecting spheres. The use of such species was
often not shared by traditional know-how practitioners, which will be addressed
here as “closed knowledge pool”. Contrarily some of the know-how were very
common to all and were openly shared hence addressed as “open knowledge

pool”. The sampled community contained people from both kind of knowledge
pools and hence are mixed.
This is the first report of medicinal use of macrofungi from the state of
Gujarat in Western-India. Moreover, the TEMPs documented practices claimed for
several species are also novel. Of all the 23 species documented those with
specific uses will be studied further for their candidature regarding
pharmacological evaluation.
2.2.3 METHODS
2.2.3.1 Location and data collection
Gujarat harbours rich biodiversity withholding 13% of countries plant diversity,
with a 15% of 29 tribes nurturing traditional knowledge regarding 750 medicinal
plants of 1200 general plants. The present study was contained within the Jessore
Sanctuary, in Banaskantha, in the Northern part of the state and the Purna Wild
life sanctuary in the Southern part (Fig 2.2.1). The details were furnished by the
local tribes, of which, the Ghanashia and Rabaris were from Jessore Community
(JC) and Dangi people from Purna Community (PC). The present report deals
only with the medicinal aspects of the ethnomycology, with respect to its
ecological niche.
2.2.3.2 Documentation of tribal mycomedicinal practices
The collection of materials was done by S. K. Lahiri, with prior permission of the
Department of Forest, and the documentation of which are endorsed under the
Biodiversity Act. The samples were identified with the help of literature (Singer,
1975; Leelavathy, 2000; Lincoff, 1989; Pegler, 1986), and an eminent taxonomist,
Dr. A. B. De, Raj College, Burdhwan, West Bengal (Lahiri and De, 2007). Total 40
people were considered for study of which some were excluded if information was
vague. The informants were asked to respond to the queries of the questionnaires
prepared in accordance to the study.
2.2.3.3 Consensus analysis
Consensus analysis of TEMPs in terms of Factor of informant consensus (Fic) was
done to test the reliability, homogeneity and the extent of selection of certain

plants for treating an ailment. Fic was calculated as reported earlier
(Subramanyam and Newmaster, 2009), Fic = Nur – Nt /(Nur – 1). Wherein, Nur is
total number of reports within the community for a particular ailment and Nt is the
total number species used for that particular ailment in the community.
2.2.3.4 Higherarchical agglomerative clustering
The hierarchical agglomerative clustering of species was done from Euclidean
distances in turn calculated from binary scores of the 3 factors elaborated below.
In order to characterize the practices and the involved species, 3 factors
influencing it were devised. The presence of the desired traits in all the 3 factors
were ascribed the value of one, whereas for the undesired traits, zero. Based on
the binary data, a dissimilarity matrix of Euclidean distances was subjected to
hierarchical agglomerative clustering based on with group-average linking rule
(Hintze, 2007). Use of species for general or specific ailments, open or restricted
sharing of the know-how within the community and storage of species for later use
are the 3 factors that were used to classify the species.
The ailments addressed were found to be either general (convalescence,
good health, strengthening) or specific (for a particular disease/ailment). Species
used for general practices were scored as 0 and specific as 1, because the latter
was more important over the other.
Same or different practitioners shared the use and identity of some species
with others people of that community (scored as 0), whereas for some species the
practice and identity was kept secret (scored as 1). It was hypothesized that the
use of the latter is more critical and such species may be important.
It was also noticed that some species were preserved for later use. The
questionnaire prepared was made to accommodate this query. If the practitioner
desired to store the species for later use, then the score of 1 was assigned, or 0 if
not stored, as storage would mean that they were important for latter use.
2.2.4 RESULTS AND DISCUSSION
Since ages mankind has bioprospected the biodiversity that was available in their
vicinity. The traditional medicinal practices established by tribal people, entirely
dependent on natural resources, tend to retained ancient knowledge as survival of

the race is a crucial issue. Habitat erosion, deforestation and ever shrinking
traditional knowledge pool can negatively influence the furtherance of such
practices that are essential for the dependent communities. Moreover, they are an
integral part of the future arsenal for drug discovery. Thus identification and
documentation of such practices are of prime importance as of now. The ethno-
myco-medicinal traditional practices of the tribal from two communities were
documented and analyzed to establish the quality of various practices and
characterize and segregate them.
2.2.4.1 Documentation of ethnomycomedicinal practices
Of 20 informants consented in each community (total 40) 15 were short-listed and
interviewed. Those presenting vague or ambiguous practices were excluded. For
the sake of homogeneity of the study the types of informants were equi-
proportional between both the communities. Of total 15 candidates of a
community, 3 were traditional medicine practitioners, 10 were farmers and 2 were
housewives. The TEMPs were observed to be widely different between both the
communities. The types of species also varied with respect to their taxonomic
origin and ecological niches. The Traditional ethnomycomedicinal practices
revealed around 23 total species which were recognized based on the rigorous
cross-checking of answers to the questionnaires. The number of TEMPs found in
JC was much lesser to that in PC. The JC reported 5 TEMPs in comparison to the
18 TEMPs from PC (Table 2.2.1). All macrofungi are arranged with respect to
their local names, taxonomy, hosts if any, their respective uses and their
ecological niches.

unknown species (Clavariaceae)
More-pankh (peacock feather)
It is used in diseases like pneumonia, constipation, and eczema. It is also used to treat children suffering pneumonia or pneumonia like symptoms. Around 5 to 6 entire fruiting bodies are triturated fresh with water for several times to form a uniform paste. The paste is consumed orally for pneumonia or constipation but is applied topically for eczema. Generally for pneumonia 1 tablespoon is administered for 3-5 times on different days. For sever constipation same dose is given after dinner for 2 to 3 days. In case eczema the affected area is covered with the paste and bandaged. This is repeated till recovery is evident.
2 Coprinus comatus (Cc) (Coprinaceae)
Ajjio It is mostly used for skin related diseases like lesions, bruised and infected skin, or for wound healing. The part of the fruiting body used in these cases is the cap and not the stipe. To be more specific the cap is opened and the spore bearing gills are applied to the affected area directly, which is then bandaged. It can be said that the spores are given the prime importance. The spores are applied till the healing is considerable.
3 Phallus (Ph) unknown species (Phallaceae)
Datto (button)
The cap is crushed in mortar with water and applied on wound, skin infections, boils, or lesions but is not bandaged. The application is repeated twice everyday for 3 days or longer if needed.
4 Lepiota cristata (Lp) (Clavariaceae)
Chatri (umbrella)
The entire mushroom is crushed in mortar and applied on the boils to speed its maturation and the regression. One or two applications are sufficient to treat.

2.2.4.2 Types of ailments treated with macrofungi
JC engaged macrofungi entailing treatment regimes for pneumonia, constipation,
eczema, bruised skin infection, lesion, boils and wound healing. Whereas, PC
employed macrofungi species for immune enhancement required in specific
diseases apart from addressing ailments like bruised skin infection, edema,
mumps, measles, chickenpox, mastitis, boils, wound healing, rashes, lesions,
pimples, impetigo, pustules, fissure and inflammation in general, employing
macrofungi. The latter community was found to address a wider range of ailments
countered by TEMPs.
Relevance of Species and its TEMPs
Cc (Ershova et al., 2001; Efremenkova et al., 2003; Yang et al., 2003; Fan
et al., 2006; Luo et al., 2004; Badalyan et al., 2003) and PL (Chen et al., 2006;
Kim et al., 2005; Yeon et al., 2008) are the only species for which substantial
amount of bioprospecting and bioactivity is already done. Two separate species
belonging to the genus of Tt are reported to have antioxidant (Puttaraju et al.,
2006) and neuritogenic (Qi et al., 2001) activities, which are not directly related to

the TEMPs recorded by us. TEMP related activity of Dictyophora indusiata, a
species dissimilar to local variety Dp, is reported to posses anti-inflammatory
effects attributed to (1→6)-branched (1→3)-β-D-glucan (Hara et al., 1982). This
corroborates well with the local TEMP (Table 2.2.1, No. 14) thought it seems to be
a different species. TEMP of Bv was reported for other species used for healing
abscess and other wounds in animals (Lans et al., 2007). Pm is known to possess
antioxidant activity that may be an integral part underlying its TEMP (Chang et al.,
2007). Rest of the TEMPs and the species are reported here for the first time to
the best of our knowledge.
2.2.4.2 Informant Consensus of TEMPs
Consensus indexing has been widely practiced for evaluating the reliability of the
traditional knowledge. Most of the ailments treated by the Purna community had a
better informant’s consensus index than the Jessore community. PC used a total
of 18 species for various ailments but JC employed only 5 species. Jessore is in
the North of the state at the border of Rajasthan and has many dunes with
patches of sparse forest on hills as it receives very scanty rainfall. Purna is
located in the southern region of the state, which has dense dry deciduous forests
and receives heavy rainfall. This geo-climatic difference can influence the density
and the diversity of macrofungi available in a particular geographical location and
can leave the traditional practitioner with meagre resources than others with
access to a greater biodiversity.
Any-how, such factors may not be the final arbitrators because the quality of
know-how may have fewer but rarer significant practices within the limited
resources with respect to the varying ecological niches. Good consensus values
should be a help in identifying the important species. Thus, such a marker that
can attach a range of values to evaluate the reliability of the traditional knowledge
can be of great importance for pharmacological research as well. The credibility of
the consensus analysis regarding both the aspects in TEMPs was assessed for
the current small and mixed knowledge pool.
The analysis of Fic (Informant’s consensus index factor) revealed varied
outputs (Table 2.2.2). The values were high for most of the ailments ranging from
0.9 to 0.928, except three ailments, which gave erroneous results due to only 1
report causing the denominator to be 0. In PC, 11 diseases scored the maximum
2.2 Documentation of TEMPs
44
DOCUMENTATION & DATA ANALYSIS
Chapter-2
indicating no options to the species employed, but 2 ailments were low scoring
with several options. Certain scores ran into negative figures because they had
more number of species (Nt) and lesser number of reports (Nur). The multiplicity
of species is due to superficially indistinguishable closely related macrofungal
species, which is common for polypores of the same genus. Such may not be the
case with plants. Some times several species of a genus may be closely
associated chemotaxons. Thus either of them may serve the purpose as the
active compound may be conserved in most of them. Pharmacologists screening
for such active molecules can isolate it from either of them, but in such case Fic
can be misleading as it remains unattended by the consensus paradigm.
The negative values also show closed knowledge pool causing lesser or single
reports for Nt > Nur (number of species > reports), which is also true for Nur = 1
and hence Fic = infinity. Thus all values below zero belong to closed knowledge
pool, but for Nur > Nt closed pools are also possible. Fic is impaired for smaller
studies, as Nur has to be > 1 and Nt has to be > Nur to get only positive values.
Moreover, due to ecological challenges like habitat erosion and species dilution,
the effective species might become rare, which will stress the practices and can
have two possibilities. If no alternates are available then traditional knowledge
might become extinct as well because of the lack of practice over generations. In
such cases of rare practices, Nur may be 1 and Fic will be ∞. If several alternates
to the species are available then another possibility arises, wherein Nt may be
high due to dilution of know-how. The Fic value is indifferent to such cases.

Use of each species for multiple symptoms of the same ailment may cause
higher Nt which can be deceptive as Fic will be low. The Consensus value is rigid
as all the plants used for the illness are treated equally as they may have lower or
higher efficacy. Thus dynamic treatment is needed which treat all the species as
case-to-case basis. The identification of the most effective species of several
options for a particular ailment is the target for molecular investigations.
2.2 Documentation of TEMPs

For objectives like drug discovery consensus value may be deceptive as
one of the several species may be very effective, but will be enshrouded by other
species causing low consensus value. Thus, preference given to one species over
others can mark its greater efficacy over others and has to be incorporated in the
estimates.
Moreover, if one species is used in different illnesses which are alike then
the community knowledge may not have discrepancy but will have lower richness
as lesser numbers of species are used for more diseases. Thus, not only the
health but the wealth of the community knowledge is important as well but this is
not addressed by Fic. Hence, this analysis is not very successful in the current
scenario and yet other need based analysis addressing other variables is
required. Such factors can be used to segregate the practices or species.
Hierarchical agglomerative clustering can be one such simple tool.
2.2.4.3 Clustering analysis
Some excellent studies on the cultural significance of the mushrooms (Garibay-
Orijel et al., 2007; Pieroni, 2001) seemed to be from open knowledge pool as the
know-how of species usage was common. Moreover, the application of such
species was mostly addressing general health remedies. The present study
differed in both the aspects. The knowledge pool and the practices or application
of species within a particular community is found to be an admixture of both
situations. In addition to this, the aim of the study also differed as identifying the
corner-stone species was essential as explained above. The tailored observations
addressing the current requirements were made to segregate the species based
on three aspects of usage and know-how, which could easily isolate the corner-
stone species.
The species used for specific practices attending a particular critical-
ailment is more precious than those used for general (non-critical) purposes as
strength giving and recovery from illness. It was observed during the study that
the know-how of such species employed for specific ailments were known by few
practitioners, some of them being traditional medical practitioners, immobilized the
knowledge. This caused the existence of the closed knowledge pool co-existing
with the open knowledge pool. Thus such species can said to be more important

regarding medicinal values than the general ones. Species stored for later use
were found to be important, and hence needed to have preeminence over others.

Hierarchical agglomerative clustering of species based on the presence or
absence of three factors mentioned above revealed a typical clustering pattern
(Fig 2.2.2) with group-average linking rule generating best cophenetic correlation
coefficient (0.9968) and delta value (at 0.5, 0.035; at1.0, 0.052). The 1st cluster

Chapter-2
(Rk, Kk, Tm, Tu, RA, R and Pt) separated at distance value of 1 of total 6 minor
clusters.
The 2nd cluster had L2 and L1 (distance value 0.9) as outliers to the 3rd
cluster. Sc, Lp, Ph and Cc separated from the rest at 0.77, where 3 minor clusters
were observed. Tt (0.65) was outlying a cluster of Rd, Po, Pr, Pm, Pl and Pd in
turn separating from the last cluster (0.57) of Dp, Bv and Xy. L1 and L2 have
TEMPs alike 1st cluster marked by non-specific usage (aiding recovery from
illness or strengthening), but are outlying to the rest (with ailment specific TEMPs)
because they are stored for later use.
The 3rd cluster includes TEMPS for specific ailments, yet it is an outlier to
the rest as it is not stored being prone to quick decay. Although Tt has specific
TEMP and is stored like those in the following clusters it is a singleton because it
is in open knowledge pool. The 6th cluster is separated from 5th as the later is
stored and former isn’t. The 5th cluster was mostly comprised of polypores
because all of them do not decay easily unlike those in the 6th cluster, which are
soft fleshy and perishable species.
Thus storage of the species is directly related to its perishable nature and
not necessarily to its medicinal value alone. Moreover, the storage parameter
gave intermingled clusters and hence is not a potent factor to segregate the
species. At the same time species involved in general (clusters 1 and 2) and
ailment specific (clusters 3 to 6) treatments were segregated.
This is a significant attribute as further investigations on medicinal
potentials are to be done on those species which have ailment specific
applications. It is also observed that the species were well segregated along the
knowledge pool paradigm.
TEMPs which were not shared in the community were found to address
important and specific ailments, though some specific TEMP related species were
in open knowledge pool. Species with specific TEMPs in open knowledge pool
were largely related with skin related disorders, which were less serious that those
specific TEMPs in closed knowledge pool.

2.2.5 CONCLUSIONS
In comparison with the Jessore the Purna community revealed several significant
TEMPs, though both the communities contribute to usages reported for the first
time. The mention of TEMPS involving species like Xy, Ph, Lp and Sc from JC
and Tt, Rd, Bv, Pd, Pr, Po, Pm and Dp from PC are novel.
Preliminary bioprospecting by simple binary clustering could characterize
the species-practice data matrix, wherein the edible mushrooms used for non-
specific ailments can be potential sources of nutraceuticals. Other species
addressing specific ailments will be further studied for their pharmaceutical
potential. Fic gave ambiguous results which can be attributed to several reasons
like non-plant study, heterogeneous knowledge pool (closed and open) and
comparatively smaller subject size. Herein, the health (reliability) of the community
knowledge was better depicted by multiple factors/markers, rather than single Fic
value, which was useful in capturing the wealth (richness) of community
knowledge as well. Fishing of promising practices from the pool of vague
practices could be grossly achieved to an extent, which for fine tuning at the level
of individual species will need more number of markers. For a detailed
pharmacological evaluation such an analysis, will be useful in identifying few
potent species from a big database.

2.3 ISOLATION OF POTENT SPECIES BY TEMPLE
2.3.1 ABSTRACT
The colossal scale of biodiversity can challenge bio-prospecting if each species
has to be addressed one by one. Traditional ethnomedical practices can be a
potent yardstick for narrowing down to species engaged in practice for
approachable and tangible out puts. Reverse pharmacology led identification of
active fraction and pharmacophore was the intended frame of research. In order
to prioritize on few of many species as lead sources addressing drug discovery,
Traditional Ethno-Mycomedicinal Practice Scores (TEMPS) were ascribe to
analyze practices within and between two communities from Purna and Jessore
region in the Northern and Southern Gujarat. Thus the evaluation of the sum total
of the pattern of influences of various factors involved in shaping the TEMP data
matrix was addressed as Traditional Ethno-Mycomedicinal Practice Lattice
Evaluation (TEMPLE). Of both the communities, Purna community, was found to
be richer in traditional know-how. Phellinus durrisimus and an unidentified species
surfaced as potent contenders.
2.3.2 INTRODUCTION
Over 50 million years termites and ants of the tribe Attini rearing and consuming
macrofungi (fruiting body visible with naked eye is addressed as macrofungi
(Chang, 1992)) are known to be the frontiers of myco-bioprospecting (Muller et al.,
1998). The advent of Ethnomycology was witnessed long before the very term
being coined by R. Gordon Wasson (Wasson, 1967), who also unleashed the
depiction of “Soma” as a mushroom summed up in 120 solkas. Only 10% of
macrofungi are known and 5% are rendered useful (Hawksworth, 2001), of which
8.5% macrofungi are reported from India (Natarajan, 2008). Around thousands of
species are theoretically estimated (Lahiri, 2008) in Gujarat as per the yard sticks
defined earlier (Hawksworth, 2001), if so, a rendezvous between biodiversity and
bioprospectors remains uninitiated.
Failures witnessed earlier in bioprospecting (McClatchey, 2005) can be
attributed to the chasm between non-specific practices and highly specific target
screening programs. Through practices spanning within various multivariate
dimensions, the present endeavor, by employing TEMPLE, targets at filtering

outliers and clusters as feasible lead-sources is indispensable in drug discovery
programs. The semi-quantitative clustering aided approach helped us in
identifying the pharmaceutical and nutraceutical groups. Further in the direction of
isolating the working group of species and identifying the primary contender
species the following evaluations are done. In addition to this the quality and
quantity of the TEMP are used to gauge the merits of the respective communities.

The answers to queries were scored as per the scoring system given below
(Annexure 2, Table 1) and the sub indices were calculated from the minor indices,
which in turn gave the main indices used to derive the final compound index
called as Traditional Ethno-Mycomedicinal Practice Lattice Evaluation Score

Non-activity index = (Decisive Index) x (Positive Critical Index) (Negative Critical Index)
Decisive Index = EI x FI x KTI x NGSI
Positive Critical Index = CKR X DLI
Negative Critical Index = DSI X TI

healing Indices (WHI) were scored by multiple facets of treatment of ailments. Co-
species priority index (CPI) is used to highlight importance of one species over
another. Mode of Application Index (MAI) stressed upon the mode of application
or consumption. Economic index (EI) is adapted to the necessary modifications

scored lower than those done only in lieu of prime economic favours. Which
species would be the subject of research is the matter of prime interest?
Addressing it Feasibility index (FI) scales the factors as perceived abundance
index, PAI (Garibay-Orijel, 2007). To compare the biomass available the dry
weight of each fruiting body (Weight Index, WI). The possibility of culture isolation
(Culturability Index, CI) for fermentation studies and DNA isolation from the
retained samples for pharmacophore gene-fishing (Genomic Index, GI) were also
addressed. From these sub indices, the main index FI was calculated as FI = (PAI
+ CI + GI) x WI. Knowledge Transfer index (KTI) was modified (Garibay-Orijel,
2007) as transfer can be horizontal (KTI-h) , i.e. from one family or practitioner to
others of same community, or vertical (KTI-v), which is the transfer of knowledge
from one generation to another, essentially within the same family. The main
index was calculated from the sub indices as KTI = KTI-h x KTI-v. Novel Genus
or Species Index (NGSI) advocates it to have a better scope of novel molecules
yet unattended, rather than those which are commonly known. Dereplication from
literature index (DLI) is an index to refurbish the TEMP by its present status with
respect to the amount of work done based on literature review. DLI was calculated
as, DLI = DLIss x DLIos X DLIsub ; where DLIss is DLI for same species. DLIos
is DLI for other species of the same genus, intended to relate between the extent
of diversity of activities and strength of chemo-resemblance within the genus.
DLIsub stands for DLI of similarity or difference of growth substrate for same
species as different geographical locations may influence chemotype diversity.
Doctrine of signature index (DSI) is used to avert any irrational correlation
between the species and TEMP based on false beliefs. Toxicity index (TI)
watches over toxic or adverse drug reactions.
Community knowledge richness index (CKR) of TEMP from Jessore
Community (JC) or Purna Community (PC) was added respectively to imbibe the
integrity of community know-how level. Some communities recognize only
superficial noticeable physical changes, whereas others recognize a greater
diversity of diseases, further classified into several coexisting symptoms, attended
with or without rituals. The fact that a community with better score may have
advanced know-how, can hopefully resolve discrepancies between the similar or
different practices of two unrelated communities using similar species. In addition

community is theoretically the maximum possible value for any overlapping
disease)}. Sdn = {Total number of macrofungi Species used to treat that particular
disease (for first disease n=1) tagged JCD1 or PCD1}. For TEMPs of a sampled
community engaging more that one species, a totally non-overlapping disease will
be addressed by only one macrofungi and will have maximum disease value
(DVn), as its Sdn will be one. But if the same is overlapping, then the disease
value (DVn) is addressed by multiple macrofungi, and thus its partial value will be
lesser for higher Sdn. The sum of DV1 to DV n yields the penultimate index species
value Ma, calculated from the disease values, only for those diseases/targets in
which the particular macrofungi species is used.
Ma = Σ DV1 to n = (DV1 + DV2 + - - - - + DVn), where DV1 to n is the disease
value of the individual diseases and a of Ma is any species of 1 to n, all from the
same community.
Disease Overlapping per macrofungal Species (DOS) can be calculated by
summing each of the species value of a community as given under,
DOS = Σ Mx = (M1 + M2 + - - - - + Mn), where, x = sum of 1 to n number of
macrofungi from JC or PC.
Finally the Community Knowledge Richness was calculated as,
CKR = [(DOS x SDR) + St + Dt + Tk ]
Higher value of DOS index would indicate more number of non-overlapping
disease targets and lower would signify grater amount of overlapping disease
targets per macrofungal species. In totality the higher value of index can be
interpreted as wider number of targets, thus withholding appreciable potential as a
richer database for lead search.
These indices can be broadly categorized into multifaceted first and second
order sub-groups of indices. The main indices can be divided into two first order
sub-groups the Activity group (CPI, WHI, AII, MSI, AMI and MAI) and Non –
activity group of indices. The activity group can be further divided into second
order sub-groups as Core group (WHI, AII, MSI and AMI) and Shell group (CPI

and MAI) of indices. Non – activity group can also be bifurcated into Decisive
group (KTI, FI, EI and NGSI) and the Critical group (CKR, TI, DSI and DLI) of
indices. In the TEMPLE equation given above the Critical group has been divided
to third order sub-group of positive (CKR and DLI) and negative critical indices (TI
and DSI) with respect to their good or indifferent and bad effects on the practices
made evident in the analysis.
2.3.3.3 Data Interpretation and Statistical analysis
The data interpretation and statistical analysis were done as reported earlier
(Garibay-Orijel, 2007) using NCSS (Hintze, 2007). Normal TEMPEL scores were
used for analysis but were scale down by 4√ for legitimate representation.
2.3.4 RESULTS AND DISCUSSION
Drug discovery being time consuming and finance intense, advocates the catch
‘fail first, fail cheap’, reducing the multiplicity of leads failing to through various
phases. Idiosyncratic leads identified by screening non-human host can be
effectively replaced by validated TEMPs in order to increases the chance of the
leads to succeed in the human trials by several folds.
2.3.4.1 Documentation of ethnomycomedicinal practices
The closed knowledge pool marked by reluctance of the practitioners to share
their traditional knowledge afforded only few know-how sharers. Of two, the first
category included species with general and non-specific medicinal practices (in
diet, for convalescence or said to have general strengthening and energizing
effects). Second category encompassed macrofungi (14 species) with specific use
against ailments or diseases. The practices engaging these species are
communicated elsewhere.
2.3.4.2 Traditional Ethno-Mycomedicinal Practice Lattice Evaluation
(TEMPLE)
Of all the 14 TEMPs reported, nine were from PC and five from JC. Higher
numbers of TEMPs reported from PC couldn’t be the only valid reason to adjudge
it as the better community, because other community richness analysis had to be
harnessed in order to make it robust. The summary of practices reflected by the

scores of macrofungi is given below (Annexure-2, Table-2) for all indices
calculated as per the specification given above (Annexure-2, Table-1).
TEMPLES (Fig 2.3.4A) revealed Rd (3394.65) and Pd (1920.31) as the
high scorers, of which the former without NGSI was (1073.5) 1.8 times lower to
Pd. Thus, analysis of the underlying factors causing so rather than direct
numerical interpretation seems to be safer for decision making. The score of
mainand sub indices are given below (Annexure-2-Table 5 and 6).

The activity group formed the crux of the study as it addresses the
pharmacological activity of the species underlying the TEMP, rest of the indices
were employed to rationalize a doable task within the given frame of resources
and objectives. In the activity group, the second order core group was directly
linked to the biological activity unlike the shell group. Core index (Fig 2.3.4B)
delineated characteristic scores for Phellinus complex being the highest. The
Shell index, an adjunct of Core index, had Tt and Xy with highest, progressing Xy
beyond Pd and Rd in Activity index. The species that are favoured are often used
up soon being rare, thus other species are opted, though the most coveted ones
may have better efficacy than others. In such cases frequency of use may be
misleading, if not coupled with factors as CPI. Xy from Jc and Pd from PC were
some of most favoured. MAI is an index that can deliver tangible outputs as the
mode of consumption not only correlates with the toxicity but also with the
possible effect of the drug. From both communities, MAI elevated Xy and Tt orally

consumed followed by Pd and Rd inhaled after heating, correlate to presence of
anthraquinones that sublimate on heating.
In non-activity sub-group, for decisive index, Rd scored highest because of
NGSI, barring which Pd surfaced above all species followed by the Phellinus
complex paralleled by Tt but left behind by Cc from JC. The values of sub index
KTI-v were entirely reflected in the score of KTI, rather than KTI-h as there was no
seepage of knowledge outside. Xy alone from JC and all species from PC all
macrofungi were age old practices, advocating for community knowledge
richness. As hypothesized, pre-eminence was imparted to the species, wherein
costlier services were rendered for critical and serious diseases, ailments or
disorders, reflected by EI. This notion didn’t fall in place for Tt that had higher
prices because of its edibility and the practice of storing it for later
immunostimulating and diseases resistance use. Practitioners charged for
collection and treatment involving Cc, Sc from JC and Tt from PC, but non-
professionals rendered services free (Xy and Lp) or left it to the beneficiary (Ph,
Bv, Dp, Rd, Pd, PL, Po, Pr and Pm) with barter options. FI is set in course with the
classical track of drug discovery harnessing reverse pharmacology by bioactivity
guided fractionation of active extracts, requiring a sizeable source of biomass.
The sub indices PAI, CI and GI, were multiplied by WI to amplify the importance of
larger biomass as an alternate to macrofungi that are nor small neither abundant.
On the other end if a species is abundantly available, but weighs only few
milligrams, then a large quantum would be needed for active principle isolation. If
this is not feasible then, studies can be made on its fermentation extracts
engaging pure culture isolates. This stands secondary to direct isolation of leads,
as the diversity of secondary metabolites are greater in fruiting body phase,
especially in situ, than the asexual mycellial stage in artificial milieu. If the modus
operandi would entail identification of genetic markers, then GI and CI would
stand for prominence. If isolation of metabolites from solid or liquid state
fermentations were intended then CI would have been of greatest value. In such
case, unlike the frame of this research CI and/or GI would have been valued
higher than PAI and WI. Moreover, the Decisive index apparently favoured
species from PC, which seemed to be under the influence of FI. Geographical and
climatic conditions may be one of the limiting factors regulating FI in terms of
abundance and size of fruiting body. Factors like lower rainfall in JC as compared

to PC may partially weaken the stand of contenders from JC. Xy and Ph,
advocated to have potent activity, were now turned down by FI fine tuning the
Decisive index. The Negative Critical index was lacked any presence. Positive
Critical index down-weighed JC by CKR and DLI, but PC.
The CKR score of Tt, Dp and Rd seemed to offer lot of scope in line with
Bv, Pd, Pr and Po, which were ahead of Pm and PL. Other than Cc rest of the
species from JC vouched by DLI were not visible in Positive Critical index due to
lower CKR than PC. Comparison between two communities showed PC (283.30)
scored 4.64 times (Fig 2.3.5A) better for CKR than JC (61.0, Fig 2.3.5C). The total
knowledge of both the communities (Tk) about all the kinds of diseases/targets
addressed could not be estimated due to conservative approach of the
practitioners, because of which CKR had to be calculated without it. The total
number of diseases (Dt) and macrofungal species (St) was higher for PC (16 and
9) than JC (7 and 5), respectively.
Species disease ratio (SDR), calculated from disease values (Annexure-2-
Table 3 and 4), greater than one is desirable, which was true for both the
communities, though SDR of JC (1.4) was lower than PC (1.78). Finally, DOS
nailed the end of conflict for PC (145.11) that was much higher than JC (61). The
predicament of DOS was dictated not only by the higher number of species and
diseases from a community, but also by the quantum of non-overlapping
diseases, which being 42.85% for JC (3 of total 7 diseases) in comparison to the
56.25% for PC (9 of 16 diseases), seemingly played its role. Moreover, although
JC had more overlapping diseases, yet within the smaller fraction of PC the extent
of overlapping was greater. Evolving such TEMPLE data matrix for lesser
generalization (too much overlapping) by exclusion of such practitioners can be
rewarding, but is only feasible when a sizable scoop of community (practitioners)
is sampled.
The JC depicted diseases like pneumonia, constipation, eczema, which
were high scorers (5) with bruised skin infection, lesion, boils and wounds, scoring
its half (2.5). Whereas PC exposed diseases like immunostimulation
(prophylaxis), boils, wounds, rashes, lesions (psoriatic), pimples, impetigo,
pustules and fissure scored most (9) for DOS, followed by bruised skin infection
with half of the high score (4.5). Edema (on physical insult), mumps, measles,

Chapter-2
chickenpox, and mastitis were low scorers (1.5), unlike inflammation (ailments
which could not be classified under any specific inflammatory disease, but said to
have all five hallmarks of inflammation, were also considered), which scored the
lowest (1.23). AMI was not only the highest recruiter of species (71.43%), but also
a leading source of overlapping targets. Though MSI followed close-by with 64.3%
species covered, yet its contribution to overlapping diseases was minor, because
the targets were opined to be different for the diseases. AII captured 57.15%
species which is more considerable than WHI containing only 42.87%. DLI is a
temporal index subjected to change in scores with respect to the increase in
numbers of reports on various species. In JC except Cc (5) all the other species
secured a substantial DLI score of 100 (Xy, Ph, Lp and Sc). Whereas in PC, Tt,
Rd and Dp were high scorers (100) closely followed by Bv, Pd, Pr and Po (80). To
some extent Pm (60) was a distant bystander unlike PL (5) that was swept away
(Fig 2.3.5A). A low DLI score would only mean that it has lesser scope of work,
which has to be exploited accordingly. The influence of DOS, DLI related sub-
indices and WI are clearly visible (Fig. 2.3.5B and 2.3.5D) on species from JC and
PC. NGSI, DSI and TI are excluded as they are indifferent to all except Rd
favored by NGSI.
2.3.4.3 Multivariate analysis
From heat-map high and low scoring outliers could be easily identified in
both the dimensions. Hierarchical agglomerative clustering of species based on
the main indices (Fig 2.3.6A) revealed three major groups, as Group A at 155.16
(Pd), Group B (Cc, Lp, Sc, Ph and Xy) and Group C (Rd, Po, Pr, Pm, PL, Bv, Dp
and Tt) at 80.58 dissimilarity distances. Group B and Group C had Cc and Rd as
outliers to the co-subgroup contained Lp and Xy independent of Sc and Ph co-
lying. In Phellinus complex (excluding Pd) of Group C, PL separated as a
secondary outlier followed by Pm, inturn separated form Po and Pr with a
dissimilarity distance below the cutoff value of 1.0. The other subgroup in Group C
had Bv outlying the co-lying Tt and Dp. In heat map of the indices clustered by the
species, (Fig 2.3.6A), CKR separated initially as an outlier, followed by FI, DLI and
NGSI. Rest of the indices separated as two closely related clusters (CPI, WHI,
MAI and EI; AMI, MSI, AII and KTI), which were further separated from each other
with minor dissimilarities.

The influence of activity indices (Fig 2.3.6B) was suppressed by non-activity
indices. Clustering of species by only activity group of indices exhibited early
trajectory of Phellinus complex, within which Pd was found to be an outlier. Of
other three groups Tt was the most dissimilar outlier and Sc and Lp were co-liers
with dissimilarity higher than other groups. The third group had Xy as a singleton
along with Bv and Cc as co-liers, dissimilarity of which was greater than the fourth
group having Ph as an outlier and Dp plus Rd as co-phenons. The pattern of
clustering of species (Fig 2.3.6C) done with non-activity group of indices was
found to be similar to clustering of main indices.
`Amongst the second order of indices, the basic clustering materialized by
Core group of Activity Indices was influenced by Shell group of indices by
triggering cluster shift of Pd and Rd apart from several other contenders (data not
shown). The clustering of Critical group of Non-activity indices was unique
emphasizing its importance, but was later influenced by Decisive group leaving its
strong imprint on the final TEMPELS clustering (data not shown). Thus it is
important to cluster at all levels realizing the cluster shift with respect to high and
low scorers for studying the influence of indices made to assist decision making.
Multidimensional scaling (Fig 2.3.7A) by non-metric multidimensional
scaling (NMMDS) yielded 1st (65.92%) and 2nd (94.08%) dimension with 2.04 and
0.87 Eigen values supported by a stress of 0.0236. Pd and Rd are again outliers
to two clusters, of which one had Lp, Sc, Ph and Xy and the other cluster had
three sub-groups with Cc separated from rest of the Phellinus complex followed
by Bv, Dp and Tt. Major transition of Cc is in 2nd dimension close to PL implying
DLI as a major role player in the 2nd dimension. Unlike Cc, Lp is observed to differ
for EI and core group of indices.
In Principal components analysis (PCA) of the species (Fig 2.3.7 B) first
two components that entailed total variability of 53.81% and 87.26% cumulatively,
with Eigen values of 11.04 and 2.01 respectively, declaring FI and CKR as major
contributors of the variations in 1st component and DLI in 2nd. Resembling
NMMDS, PCA with rotation placed Pd and Rd far from other two groups,
pronouncing them as prominent outliers. Of the two oppositely poled, one group
composed of Cc, Dp, Tt and closely knit rest of the Phellinus clan with PL outlying,
whereas the other encompassed Xy, Sc, Ph and Lp outlying within the group. The

PCA of indices (Fig 2.3.7 C) showed weak clustering unlike hierarchical
clustering.
Spearman’s correlation analysis revealed coincidental positive correlation
of CKR to KTI (p<0.0001; 0.84) and AII (p=0.007; 0.68), contributed by incidence
of species scoring high for all 3 indices from PC. Similar case registered for MSI
(p=0.008; 0.67) and AII (p=0.01, 0.63) scorers being more feasible (FI) by either
abundance or weight if few, vouch for sustenance of such practices assisted by
closed knowledge pool. CPI was found to be almost equally correlated to DLI
(p=0.018, 0.62) and MAI (p=0.022, 0.6) suggesting that the most preferred
species have better efficacy owing to their direct consumption and that they are
not much investigated. This indicates positive outcome of the analysis, and makes
way for the furtherance of such species for pharmacological evaluation and lead
search. Moderated correlation was observed between MSI and AMI (p=0.03, 0.56)
delineating the possible role of immune stimulation against infections, alongwith
KTI and AII (p=0.04, 0.55).
Negative correlation was found to be most significant between MSI and
WHI (p<0.0001; 0.87). It was also observed that sometimes combination of MSI
and AII were also used first to ripen or aggravate and then to reduce a boil. This
was supported by negative correlation between MSI and WHI, which on
backtracking was responded as not used because of aggravating a wound rather
than healing it. It is well known that immune stimulation may cause tissue damage
by reactive oxygen species (ROS) and other enzymes released by the
neutrophils, macrophages and other cells involved in immune-surveillance
(Kirkham & Rahman, 2006). Negative correlation between AMI and DLI (p=0.019,
0.614) and FI and WHI (p=0.019, 0.618) were also found to be equivocally
prominent. The imprint of Cc being worked out for its antimicrobial activity was
reflected in negative relation of AMI and DLI, and constrains the research in this
direction alone. Contradictory relation between WHI and FI is because such
species are smaller in size and are mostly used only topically, thus required in
less quantity. This also shows that low FI calls upon adaptability for the survival of
a practice. A correlation coefficient of 0.54 depicted minor but reciprocal effect of
CPI and WHI (p=0.045). A weak correlation was sighted for negative impact of
CPI on WHI, which may indicate that the other more preferred species may be

more efficacious due to added antimicrobial and anti-inflammatory activity. All
such facets provided important insights regarding the interactions that might have
been evolving since ages to portray the current pattern of practice woven to
external and internal factors as revealed by TEMPLE.
2.3.5 CONCLUSIONS
Instead of literal interpretation form scores, the dynamics of the species trajectory
under the influence of various layers and groups of indices interestingly helps in
sidelining the lesser important species. The TEMPLE score coroneted Pd and Rd
as top charters. Pd backed by CKR migrated from the Phellinus complex due to
its greater suitability for the reverse pharmacology approach entailing animal
experiments demanding greater biomass to be extracted, pillared by its pre-
eminence over its counterparts and DLI indicating no pharmacological
investigations done. The fact that Rd scored thrice of Pd due to NGSI, though Pd
had better activity profile, indicates the semi-quantitative nature of TEMPLES and
necessitates considerations to be made at the first, second and even at the third
order of indices. CKR used to highlight PC as richer than JC can also be adapted
to analyze and compare several individual practitioners of one or many
communities, school of practices, texts and codices or other distinct sources.
Hence, TEMPLE can be a promising dynamic Swiss-knife in the pre-lead-activity-
screening tool-box.
