The genera Geomyces and Pseudogymnoascus are closely related and found in the family Pseudeurotiaceae, but P. destructans was found to be most closely related to the "Pseudogymnoascus" species, indicating that its name should be changed to Pseudogymnoascus destructans.

There are currently nine hibernating bat species confirmed with infection of Pseudogymnoascus destructans, and at least five of those species have suffered major mortality.

The fungus Pseudogymnoascus destructans, or a closely related species of fungus, has been found in soil samples from infected caves and suggests that it can be transported from cave to cave by soil, such as that carried by human clothing.
