Pseudogymnoascus alpinus Müller ascospores are described as navicular-fusiform in shape and hyaline to yellow in color.

[5] This species was initially isolated from rotten black spruce wood found under Sphagnum peat in Canada.

[5] Pseudogymnoascus bhattii Samson has single-celled, hyaline to yellow fusiform ascospores which are described as flattened on one side.

[4] Samson isolated this species from alpine tundra soil in Canada and Alaska and stated that it could grow from 10 °C to 25 °C.

[2] Pseudogymnoascus caucasicus Cejp & Milko described this species as having stalked chlamydospore-like structures and no ascomata.

[8] Pseudogymnoascus roseus Raillo has smooth ascospores that are ellipsoid to fusiform and can vary from yellow to reddish brown.

[4][5][9] Pseudogymnoascus verrucosus Rice & Currah is distinguished by the presence of warts that covers the ascospore surface.
