Humphreya

Humphreya is a genus of four species of polypore fungi in the family Ganodermataceae. The genus was circumscribed by Belgian mycologist René Léopold Steyaert in 1972. He proposed Humphreya as a genus segregate from Ganoderma, typified by Ganoderma lloydi Pat. & Har., and included Ganoderma coffeatum and the newly described Humphreya endertii.[1] H. eminii was transferred to the genus (from Ganoderma) by Leif Ryvarden in 1980.[2]

Humphreya differs from Ganoderma by the velvety cap and stipe surfaces of its fruit bodies. Microscopically, the spores of Humphreya feature a crested endosporium (the innermost layer of the spore wall). The generic name Humphreya honours Clarence John Humphrey (1882–1970), a scientist and mycologist specializing in wood-decay fungi.[1]
