Classification of the phylum Ascomycota
Subphylum Taphrinomycotina - early diverging
Ascomycota - may not be a single group -
yeasts, filamentous, dimorphic species
Subphylum Saccharomycotina - true yeasts
- some species with filamentous stages - no
sporocarps - no ascogenous hyphae Subphylum
Pezizomycotina - the ascocarp-forming
Ascomycetes - filamentous - some species with
yeast stages
