Study Notes

Basidiomycetes

Commonly known as mushrooms, bracket fungi, or puffballs
Grow in soil, on logs, or tree stumps
Mycelium is branched and septate
Asexual spores are not often found
Reproduction by fragmentation is common
Plasmogamy brings about fusion of vegetative or somatic cells
Resultant structure is a dikaryotic
Karyogamy and meiosis occur in a basidium
Basidiospores are produced on the basidium
Basidia are arranged in fruiting bodies called basidiocarps
Common members include Agaricus (mushroom) , Ustilago (smut), and Puccinia (rust fungus)

Deuteromycetes

Commonly known as "imperfect fungi"
Only the asexual or vegetative stages are known
When the sexual forms are discovered, they are moved to their respective classes.
Reproduce only via asexual spores, known as conidia
Mycelium is septate and branched
Some are saprophytes or parasites
Many are decomposers
Examples include Alternaria, Colletotrichum, and Trichoderma
