How are fungi classified? |
According to the structure upon which spores grow. |
|
|
Basidiomycota |
(Club fungi). Spores grow on club-shaped structure called a basidium. Examples: Store bought mushrooms. (Agaricus brunescens) Puff ball (Calvatia gigantea) Bracket fungi |
|
|
Ascomycota |
Sac Fungi. Spores grow into a sac-like structure known as an ascus. Examples: Baker's yeast (saccharomyces cerevisiae) Morels (morchella esculentoids) Birdsnest fungi, Truffles (Tuber uncinatum ) |
|
|
Zygomycota |
Strand like spores. Examples: Rhizopus (rhizopus stolonifer) -- commonly known as bread mold, ripe sporangia cause these to appear black. Cladosporium (cladosporium herbarum) exceedingly common organism, can appear green, brown, grey, or black on surfaces, found on dead plants. |
