The Taphrinomycotina are one of three subdivisions constituting the Ascomycota (fungi that form their spores in a sac-like ascus) and is more or less synonymous with the slightly older invalid name Archiascomycetes (sometimes spelled Archaeascomycetes; archea = ancient). Recent molecular studies suggest that the group is monophyletic and basal to the rest of the Ascomycota.[2][3]

The Taphrinomycetes are dimorphic plant parasites (e.g. Taphrina) with both a yeast state and a filamentous (hyphal) state in infected plants. They characteristically infect leaves, catkins, and branches, not roots. Taphrinomycetes form asci but no ascomata.
The Neolectomycetes are species in a single genus, Neolecta, which are the only members of the subdivision that form ascomata (fruiting bodies), and which specifically grow out of root tips. They may have a yeast state (ascospores bud in the asci).[citation needed]
The Pneumocystidomycetes also encompasses only one genus of yeasts, Pneumocystis, one of which causes Pneumocystis pneumonia in humans by developing cysts on the lung tissue.
