Basidiomycetes Flashcards
What are the 3 subphyla of basidiomycota
- Agaricomycotina
- Usilaginomycotina
- Pucciniomycotina
What are the Agaricomycotina
-Mushrooms, puffballs, shelf fungi, jelly fungi
-20k described species
-68% of all -Basidiomycetes
oldest fossil evidence ~290 mya
-Basidia produced on non-gilled hymenium
Important functions of basidiomycota
- mycorrhizal associations
- decompose lignin
- edible
- decay wood and structures
- used in paper and pulp manufactoring
Dolipore septa
- Basidiomycota only
- septal pore caps (parenthosomes)
Clamp connections
- believed to keep the n+n connection
- only in basidiomycota
Basidiomycota hymenium
- basidia
- basidioles
- cystidia
What are the prongs on a basidium?
sterigmata
-holds the basidiospore
Tertiary mycelium
- generative hyphae (thin walled)
- skeletal hyphae (thick walled, unbranched)
- binding hyphae (highly branched, thick walled)
what is the hymenophore
-tissue bearing hymeium
Hymenium on poylpores
-lines pores or tubes
Hymenium on chanterelles
-on gill-like folds
Hymenium on toothed fungi
-on small spines
Hymenium on coral fungi
-erect basidiocarps, hymenium covering surfaces
Basdiocarp compostion
- monomitic (generative hyphae only)
- Dimitic (generative hyphae and skeletal/binding hyphae)
- Trimitic (generative and skeletal and binding)
Polyporales
- poroid hymenium
- basidiocarps variable
- saprotrophic, decay large woody substrate
- annual and perennial basidiocarps
- polyporus, fomitopsis, ganoderma, laetiporus, phaeolus, trametes
