This [Inonotus hispidans G.H. Cunn.] is the same as Polyporus albertinii as indicated by Reid (1967: 164). There is a detailed description in Reid (1963: 277) where he transferred the species to Phaeolus Pat. That genus is typified by P. schweinitzii (Fr.) Pat., and characterised by a brown fruit-body similar to that seen in Inonotus species. However, P. schweinitzii lacks setae and has instead oil-filled cystidia of a type unknown in the Hymenochaetaceae. Furthermore, it causes a brown rot in the wood, while all members of Hymenochaetaceae give a white rot. We feel that these characters alone are sufficient to exclude Phaeolus from the Hymenochaetaceae.
Polyporus albertinii Lloyd is characterized by setal hyphae of the type seen in many representatives of the Hymenochaetaceae and we are in no doubt that the species belongs in Inonotus because of its monomitic hyphal system with wide, brown, simple septate hyphae.
