Jahnoporus
Jahnoporus is a genus of fungi in the family Albatrellaceae. There are two species in the genus, which have a widespread distribution in northern temperate regions. The type species, "J. hirtus", was transferred to this genus in 1980; it was formerly known as "Piptoporus hirtus". The genus name of "Jahnoporus" is in honour of Hermann Jahn (1911 - 1987) German teacher, Ornithologist and Botanist (Mycology). The genus was circumscribed by Ingo Nuss in Hoppea vol.39 on page 176 in 1980.
