Species Characteristics
Pseudogymnoascus alpinus Müller
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.[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.[2] No anamorph (asexual state) was described.[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.[3] This species was initially isolated from forest soil in Georgia. In 1982, Müller noted that the type culture was sterile.
Pseudogymnoascus destructans Minnis & Lindner was initially described in 2009 as Geomyces destructans by Gargas et al.[7] In 2013, further analysis of the phylogenetic relationship moved this species to the genus Pseudogymnoascus.[6] The conidium of this species are hyaline and characteristically curved.
This species was first isolated from infected hibernating bats in New York state. Recently, this species has been isolated from cave environments no longer inhabited by hibernating bats.[8]
Pseudogymnoascus roseus Raillo has smooth ascospores that are ellipsoid to fusiform and can vary from yellow to reddish brown. Conidia are typically hyaline in color and globose to ellipsoid in shape. The base of the conidia are truncate.[2] Pseudogymnoascus roseus is frequently isolated from soil, root and wood samples.[4][5][9]
Pseudogymnoascus verrucosus Rice & Currah is distinguished by the presence of warts that covers the ascospore surface. In contrast, the conidia are described as smooth to asperulate.[5] This species was also isolated from the same substrate and locality as Pseudogymnoascus appendiculatus.
