Notes on Taxonomy: [Edit]

“For Piptoporus betulinus, species identification is comparatively easy, but also here rDNA ITS sequence divergence indicates the presence of distinct clusters within this taxon.” Grienke, U., Zöll, M., Peintner, U., & Rollinger, J. M. (2014). European medicinal polypores–A modern view on traditional uses. Journal of ethnopharmacology, 154(3), 564-583.

“Piptoporus betulinus (Bull.) P. Karst. (known as birch polypore, birch bracket, or razor strop) is a common Basidiomycota brown rot macrofungus growing on decaying birch wood. Homobasidiomycetes were divided into eight clades. The family Polyporaceae with the genus Piptoporus was classified to the polyporoid clade, and then the antrodia clade—the Fomitopsis-Daedalea-Piptoporus group comprising brown rot fungi was identified within this clade (Hibbett and Donoghue 2001; Hibbett and Thorn 2001). Further studies of the phylogenetic relationships among members of the antrodia clade revealed polyphyly of the Fomitopsis genus and suggested that P. betulinus was phylogenetically closer to Fomitopsis than to Piptoporus (Kim et al. 2005; Ortiz-Santana et al. 2013). Recently, P. betulinus (Bull.) P. Karst. has been transferred to Fomitopsis (Han et al. 2016) and, according to Index Fungorum (2016), is classified in the genus Fomitopsis, family Fomitopsidaceae, order Polyporales, class Agaricomycetes, division Basidiomycota, kingdom Fungi, with the current name Fomitopsis betulina (Bull.) B.K. Cui, M.L. Han and Y.C. Dai, comb.nov. (MycoBank no.: MB 812646).” (Pleszczyńska et al., 2017)
