Pseudogymnoascus
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.
