What is "rugosospora"

Rugosospora is a genus of fungi in the family Agaricaceae. The genus contains two species: R. ochraceobadia, found in Africa, and R. pseudorubiginosa, found in Colombia and Mexico. These species have fruit bodies ( mushrooms) with free gills, a white spore print, and a ring on the stipe. Rugosospora was circumscribed by Belgian mycologist Paul Heinemann in 1973.
