An updated phylogeny and diversity of Phylloporia (Hymenochaetales): eight new species and keys to species of the genus

Abstract

Phylloporia is shown to be monophyletic according to molecular sequence data. Morphologically, Phylloporia is characterized by annual or perennial basidiomata, a monomitic to dimitic hyphal system, generally presenting a duplex context, absence of setae, and abundant tiny, thick-walled and colored basidiospores. In this study, specimens from China and Brazil a priori identified to Phylloporia species were revised. Phylogenetic analysis based on the nuc 28S rDNA showed that they nested within the Phylloporia clade, in which they formed eight new terminal lineages. According to this result and additional morphological and ecological data (host relationships), these eight lineages are described as eight new species: Phylloporia atlantica, P. cystidiolophora, P. montana, P. perangusta, P. rattanicola, P. solicola, P. splendida, and P. subpulla. Detailed descriptions with illustrations are provided for these new species, and their relationships with similar or allied species are discussed. An identification key for all accepted 56 species with a synoptic description is provided, and two keys to neotropical and Asian Phylloporia species are also provided.
