Aw 0.89. This mold is reported to be a major allergen, capable of causing hay fever and asthma. It is also known to rarely cause subcutaneous infections. The University of Adelaide, Australia, categorizes this microbe in the classification group "Dematiaceous Hyphomycetes", which includes it as a possible causative agent of phaeohyphomycosis (see phaeohyphomycosis).
Widely distributed in nature and considered a saprobe (weak parasite), some of its growth sites are soil, grasses, dead or dying plants (mainly herbaceous vegetation), manure, and compost. In interior environments it has been found on paper, painted surfaces, gypsum board, textiles, jute, straw materials, carpets, cellulose building materials (including wood), and in dust and air samples. Colonies are moderately fast growing, usually appearing olive-brown (or rusty-brown) to black (or grayish), with a texture that is granular to velvety.
