Pseudogymnoascus is a genus of fungi in the family Pseudeurotiaceae.
It was circumscribed by A. Raillo in 1929 for two species, P. roseus and P. vinaceus. No type specimens were retained by Raillo. In 1972, Samson designated a neotype for P. roseus, recognized three species (P. roseus Raillo, P. bhattii Samson and P. caucasicus Cejp & Milko) and synonymized P. vinaceus with P. roseus. In 1982, Müller described a fourth species, P. alpinus. In 2006, Rice and Currah described two additional species, P. appendiculatus and P. verrucosus. In 2013, Geomyces destructans the casual agent of bat white nose syndrome was transferred to this genus and is now referred to as P. destructans. Since 2006, intensive cave sampling has identified numerous Pseudogymnoascus isolates that have yet to be described.
Pseudogymnoascus alpinus Müller ascospores are described as navicular-fusiform in shape and hyaline to yellow in color. Typically, one side of the ascospore is flattened with 3 longitudinal rims. Müller collected P. alpinus from soil below Winter Heath in Switzerland.
Pseudogymnoascus appendiculatus Rice & Currah differs from other Pseudogymnoascus species by the presence of long, pigmented, branched peridial appendages. The ascospores have a longitudinal rim or are otherwise described as smooth. This species was initially isolated from rotten black spruce wood found under Sphagnum peat in Canada.
Pseudogymnoascus bhattii Samson has single-celled, hyaline to yellow fusiform ascospores which are described as flattened on one side. No anamorph (asexual state) was described. Samson isolated this species from alpine tundra soil in Canada and Alaska and stated that it could grow from 10 °C to 25 °C.
