Aspergillus ustus

A rapidly growing fungus that produces an olive-gray to drab colony within fourteen days, when incubated at 25oC (77oF). It is commonly found worldwide but especially in the tropical and subtropical regions. It can be isolated from air, soil, desert soil, sand dunes, mangrove swamps, salt marshes, sewage, mines, seawater, bird feathers, rabbit dung, wood pulp, cotton fabric, leather, bees, and plant seeds. Rarely, it can be an opportunistic human pathogen.
