Caption: Mold (Aspergillus versicolor). Conidia (asexual spores) are produced on the conidiophores (fruiting structures / sporangia). Aspergillus versicolor is very common in damp places including: gypsum boards, carpets, mattresses, upholstered-furniture and damp walls. It is commonly found in soil, hay, cotton, and dairy products. It can produce a mycotoxin, sterigmatocystin, and cyclopiaxonic acid. Sterigmatocystin is reported to be carcinogenic to the liver and kidney, and it can cause such symptoms as diarrhea and upset stomach. This genus can also cause skin infections in burn victims and the fungal lung infection aspergillosis (secondary infection to AIDS).
