Emericella rugulosa (Anamorph: Aspergillus rugulosus)

A slow growing fungus that produces a greenish colony within fourteen days, when incubated at 25oC (77oF). Numerous purple-brown cleistothecia (a round fruiting body without an opening that contains randomly placed asci containing ascospores) are produced. Ascospores are purple-red, rough and have two sinuate equatorial ridges. Dark brown specialized thick-walled cells (Hülle cells) are present. In culture, the anamorph form is also present. It has worldwide distribution and can be isolated from soil, coconut groves, bat caves, mangrove mud, rhizospheres of barley and wheat, compost, and groundnuts. It is not considered to be an animal or human pathogen.
