Eurotium herbariorum (Anamorph: Aspergillus glaucus)

A slow growing fungus that produces a yellow-green to greenish-gray colony with a yellow-brown to red-brown reverse within fourteen days, when incubated at 25oC (77oF). Orange-yellow cleistothecia (a round fruiting body without an opening that contains randomly placed asci containing ascospores) are abundantly produced. It is very common worldwide especially in the tropical and subtropical regions. It can be isolated from air, soil, garden compost, silage, course fodder, peat, desert soil, sand dunes, estuarine silt, salt marshes, mangrove swamps, polluted streams, salt water, frescoes in a monastery, sugar beets, corn, rhizospheres of oats and barley, rice, groundnuts, spices and meat products, bird feathers, paper, leather, cotton fabrics, stored copra and cacao beans, and foodstuffs. It is sometimes listed as producing mycotoxins in contaminated corn and cereal products which are toxic for mice and ducklings. It is not considered to be an animal or human pathogen.
