Rigidoporus Murrill, Bull. Torrey Bot. Club 32(9): 478 (1905)
Notes – Rigidoporus was first described by Murrill in 1905. The basionym of its type is Polyporus microporus Fr. This genus is one of the most species-rich genera of basidiomycete wood-decaying saprobes, causing a white rot in deciduous and coniferous tree. Most of the species of Rigidoporus have been described from the Northern Hemisphere (Murrill 1905; Cooke 1949; Corner 1987; Zeng 1992; Ryvarden and Gilbertson 1994; Dai 1998, 2010, 2012a, b; Hattori 2011; Zmitrovich and Malysheva 2014). Recently, multi-gene molecular phylogenies, inferred from ribosomal DNA sequence data, demonstrated the polyphyletic nature of Rigidoporus, and the generic type was nested within a clade in the Hymenochaetales. Moreover, the genus Oxyporus was treated as a synonym of Rigidoporus and most of the Oxyporus species were transferred to Rigidoporus (Wu et al. 2017).
