Abstract

Poriella subacida gen. & comb. nov., previously known as Perenniporia subacida, which causes white rot, has been documented in temperate and tropical forests. Specimens from Asia, North America, and Europe were examined, including the type specimen of Polylorus subacidus. Sequences of the ITS1-5.8S-ITS2 region, the 28S rDNA, the mitochondrial rDNA small subunit (mtSSU), and the gene encoding the translation elongation factor 1-α (EF1) were generated. In multigene phylogenies (maximum parsimony, maximum likelihood, Bayesian inferences), “Perenniporia subacida” formed a well-supported lineage, distinct from the core “Perenniporia” clade (type species: “P. medulla-panis”), and sister to the “Yuchengia narymica” lineage. We therefore conclude that “P. subacida” should be placed in the new genus “Poriella”gen. nov. Morphologically, “Poriella” is characterized by a di- to trimitic hyphal system, non-truncate basidiospores, and strongly dextrinoid, cyanophilic skeletal hyphae.
