Mushrooms,molds, mildews yeast, rust, smutsClassified by reproductive structure
Characteristics• Eukaryote• Unicellular to multicellular• Cell wall of chitin (insect bodies)• Body is made of Long filaments of
hyphae which form a mycelium• Heterotrophs– Some are parasites– Some are saprophytes (decomposers)
Phylum Zygomycota = the Bread MoldsRhizopus – black bread mold
Phylum Oomycota = the Water MoldsWater mold, potato blight, mildew
Phylum Ascomycota = the Sac FungiYeast, morels, truffles
Phylum Basidiomycota = the Club FungiMushrooms, puffballs, bracket fungi,
rusts, smuts, toadstoolsPhylum Deuteromycota = the Fungi
Imperfecti
Parts of fungi:
Hyphae -
network of thin thread-like structures that form the “body” of a fungus
• hyphae contain cytoplasm
• hyphae grow and branch until they cover and digest the food source (upon which the fungi is growing)
Mycelium - a mass of hyphae
•The mycelium is usually hidden in the soil, in wood, or another food source
The ‘living’ body of the fungus is a mycelium
The part of the fungus that we see is only the “fruiting body” of the organism
Puffball and a cloud of spores
Sporangia of breadmold
Pencillium
Mushrooms – “Club Like” Fungi or Basidiomycete Fungi
Bracket Fungi – Basidiomycete Fungi
Cup Fungi – Ascomycete Fungi
Zygomycota (Rhizopus) the Common Molds
The fungal mass of hyphae, known as the MYCELIUM penetrates the bread and produces the fruiting bodies on top of the stalks
Rhizoids = root-like hyphae The zhizoids meet underground and mating occurs between hyphae of different molds (SEXUAL REPRODUCTION)
Morels are Ascomycete Fungi
Basidiomycete or Club Fungi
Rust on corn
Rust on leaf
Smut on wood
Deuteromycota (Imperfect Fungi)
Penicillium fungi
Irish Potato Famine of 19th Century
