Microbotryomycetidae

Budding cells of Leucosporidium antarcticum, photographed by Linda barnett.

Belongs within: Uredomycetidae.
Contains: Sporidiobolus, Microbotryales.

The Microbotryomycetidae is a diverse clade of fungi, often yeasts, including phytoparasitic, mycoparasitic and probable saprobic species. The clade is primarily supported by molecular data.

Characters (from Swann et al. 1999): Spindle pole body a layered subgloboid at interphase and metaphase; nucleolus discarded at metaphase.
