ASPERGILLUS

Aspergillus genus of the Fungi Imperfecti (form-class Deuteromycetes). Those species for which the sexual phase is known are placed in the order Eurotiales. A. niger causes black mold of foodstuffs; A. flavus, A. niger, and A. fumigatus cause aspergillosis in humans. A. oryzae is used to ferment sake, and A. wentii to process soybeans. Three genera of the class Ascomycetes have Aspergillus-type conidia (asexually produced spores): Emericella, Eurotium, and Sartorya.
