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
