Genus:
Aspergillus
Species:
nidulans
Distribution:
Distributed worldwide, abundant.
Substrate:
A typical soil fungus, also known as a good decomposer of starch and cellulose.
Dispersal:
Conidia or chains of conidia easily become airborne and are dispersed by wind.
Indoor Occurance:
A common indoor contaminant. Optimal growth rate occurs at an intermediate water activity (Aw) of 0.85-0.90.
Allergenicity:
May be allergenic.
Pathogenicity:
Occasionally causes pulmonary infection in immunocompromised people.
Notes On Identification:
Not distinctive on spore trap samples. Genus can be identified on surface or bulk samples if the entire sporulating structure is present. Species identification requires mycological examination of aporulating cultures or molecular methods.
Teleomorph:
Emericella nidulans
Spore Types:
Conidia 3-4 µm in diameter, globose, roughened. Ascospores 3.8-4.5 µm in diameter, purple-red, lenticular, smooth, with two equatorial crests.
