Phylogeny and taxonomy of Phylloporia (Hymenochaetales): new species and a worldwide key to the genus

Abstract

Species of Phylloporia (Hymenochaetales, Basidiomycota) are polypores with tiny, yellowish and thick-walled basidiospores and are highly divergent in morphology. The monophyly of 35 cosmopolitan isolates of Phylloporia was strongly supported based on analysis of the nLSU rDNA gene but with exclusion of P. resupinata. Among the 19 lineages recognized in the nLSU rDNA phylogeny five new species from China, Phylloporia crataegi, P. fontanesiae, P. gutta, P. nandinae and P. oreophila, were revealed and these species are introduced with additional morphological evidence. A diagnostic key to all 23 thus far accepted species in Phylloporia is provided.
