CURRENT KNOWLEDGE & RESEARCH
Despite their importance, compared to plants andanimals we know next to nothing aboutmushrooms.
We don t even know what species grow here;how can we know if
a) something is alien, orb) if it is having any effect on the others, most of which are unknown to us?
“Research” is primarily trying to determine whatspecies grow here, indeed, what is a species.

SO WHAT?
Not known to destabilize myco- or ecosystemhomeostasis
DIRECT HARMDIRECT HARM
Conocybe filaris causes death to toddlerscrawling in grass and youths mistaking it forhallucinogen for recreational purpose.
Last death—18 yr old girl in BC in 2006.

Amanita phalloides
soon to be introduced
![Page 15: Exotic and Invasive Alien Species Workshop](https://reader035.fdocuments.in/reader035/viewer/2022071006/62c8b6e2d0414521af0efa69/html5/thumbnails/15.jpg)
Amanita phalloides
All over continental westcoast
At least 4 eastern states
Introduced with plants, soil
In one place amongimported Norway spruce
Possibly in Ontario
Soon in Newfoundland,GUARANTEED!

SO WHAT?
Not known to destabilize myco- or ecosystemhomeostasis
DIRECT HARMDIRECT HARM
Amanita phalloides 2nd commonest cause ofdeath from mushroom poisoning in NA
(A. virosa/bisporigera is #1).

Larix laricis
Where did they all come from?
![Page 18: Exotic and Invasive Alien Species Workshop](https://reader035.fdocuments.in/reader035/viewer/2022071006/62c8b6e2d0414521af0efa69/html5/thumbnails/18.jpg)
Ganoderma lucidum
Butt rot elsewhereOnly decomposer here???Where did it come from?Was it here?Did it come with young tree?
We don t know.

Conclusions1. We know very little about mushrooms2. If we knew more, suspect we have many aliens3. On the basis of our small knowledge, one alien killer is
here4. One alien killer is about to enter5. Importing plants and soil seems to facilitate alien
invasion6. We are invasion vector, facilitated by
1. Dissemination of information2. Ease of transport/travel
![Page 20: Exotic and Invasive Alien Species Workshop](https://reader035.fdocuments.in/reader035/viewer/2022071006/62c8b6e2d0414521af0efa69/html5/thumbnails/20.jpg)
Recommendations1. Hire mycologists to conduct research and fill our
knowledge gaps.2. If invasion of alien species is not desirable, legislate
against import of soil and plants for private,commercial and civil use.
3. Use the same information dissemination to educatethe public.
