The new polypore Rigidoporus pouzarii Vampola et Vlasák is described, occurring in alluvial forests, forming annual resupinate fruitbodies on lying dead stems of hardwoods, mostly Alnus species. In Europe, the species has been probably misidentified as R. crocatus, a closely related species differing by perennial, multi-layered fruitbodies and occurrence in old-growth mountain forests, preferentially on logs of Abies alba. Diagnostic features of both species are discussed and DNA sequences are also added. The name is dedicated to Zdeněk Pouzar, distinguished Czech mycologist, expert in alluvial forest fungi and our excellent teacher, on the occasion of his 80th birthday.
