Mould Identification: A Virtual Self Assessment

Excellent you have really done well.

Please find additional information below

Colonies are flat, spreading, buff to pale brown, powdery to suede-like, with slightly raised and folded centre and some radial grooves. Reverse pigment dark reddish brown.

Numerous large, very thick-walled, echinulate (rough) elliptical macroconidia with predominantly 5-6 septa but may be from 2-8 septa. Occasional spirals may be seen. Moderate numbers of mainly slender clavate with some pyriform macroconidia are present. The macroconidia are quite characteristic and diagnostic of M. cookei and further tests are not necessary. The thick walls and usually larger size of the macroconidia distinguished M. cookei from M. gypseum.  RG-1 organism.

Comment:
Microsporum cookei is a geophilic fungus which has been isolated from hair of small mammals showing no clinical lesions. Infection has been reported in rodents, dogs and rarely in humans. It is not known to invade hair in vivo, but produces hair perforations in vitro. M. cookei has a world-wide distribution.
