Classes of Sub Division Basidiomycotina
Classes of Sub Division Basidiomycotina
1) Basidiocarp Absent:
It is replaced by teliospore or chlamydospore grouped in sori, Scattered within host cell and parasite on vascular plants.
Class: Teliomycetes
E.g. Rust and Smut Fungi
2) Basidiocarp Present:
i) Basidiocarp gymnocarpous:(Open or semi angiocarpous)
(Open at its later stage of development)
Basidiospores are Ballistospores
Class: Hymenomycetes
E.g. Edible or nonedible mushroom
