A new species of Inonotus is proposed because it has a unique combination of morphological characters. No other species of the Hymenochaetaceae has all of these features (1) a pileate basidioma, (2) a duplex context, (3) large, pigmented, thick-walled basidiospores, (4) tramal setal hyphae, and (5) hymenial setae. The generic placement of the fungus is discussed and several similar species are differentiated from it.
