Four new species of Phylloporia (Hymenochaetales, Basidiomycota) from tropical China with a key to Phylloporia species worldwide.

Phylloporia (Hymenochaetaceae) is a monophyletic and cosmopolitan genus with diverse morphology. In a nuc 28S rDNA-based phylogeny specimens collected from tropical China were recovered as four new lineages within the Phylloporia clade. Based on morphological evidence and host relationships, these four lineages are described and illustrated as four new species: Phylloporia clausenae, P. cylindrispora, P. flacourtiae and P. homocarnica. The distinctive morphological characters of the four new species of Phylloporia are discussed. In addition, the phylogenetic position of P. tiliae, which was recently described from China, was confirmed in the Phylloporia clade. A key is provided for all 30 accepted species of Phylloporia.
