Species/Subspecies: Pseudogymnoascus destructans
Category: Animal pathogen
Etymology: Genus name: false naked ascus.
Species epithet: destructive.
Alternative Species Name(s):Geomyces destructans
Significance:In Europe and North Asia, the disease is not very important, because bats seem to be resistant, In North America, on the other hand, the disease has caused mass deaths among bats that goes into hibernation and is a major problem.
  [Important]   
Geographic distribution: This fungus is considered to originate from Europe where it occurs in many countries. Also found in northern Asia, but in Europe and Asia it does not cause any major problems, as bats appear to be resistant here. Recently, it has spread to North America, where it poses a threat to several different bat populations.

 "Incertae sedis" means that the taxonomic affiliation has not been established.
Macromorphology (smell): The colonies are greyish and the fungus produce a brownish pigment.
Micromorphology: The conidia have a characteristic curved shape.
Metabolism: P. destructans can utilize nitrate, nitrite, ammonium ions, urea och uric acid as nitrogen source.
Reproduction:P. destructans reproduces asexually with conidia-
Spec. Char.: P. destructans is psychrophilic and it only grows at 5-20°C (41-68°F) and, therefore, thrives on hibernating bats.
Disease/effect: White-nose syndrom (WNS) in bats.
Hosts/materialDisease/effectClinical picture or result

Virulence Factors: Urease, proteinase and superoxide dismutase.
