Taxonomy and phylogeny of the brown-rot fungi: Fomitopsis and its related genera

Taxonomic and phylogenetic studies on the brown-rot fungi, Fomitopsis and its related genera, are carried out. On the basis of morphological characters and phylogenetic evidence of DNA sequences of multiple loci including the internal transcribed spacer (ITS) regions, the large subunit nuclear ribosomal RNA gene (nLSU), the small subunit nuclear ribosomal RNA gene (nSSU), the small subunit mitochondrial rRNA gene sequences (mtSSU), the translation elongation factor 1-α gene (tef1) and the second subunit of RNA polymerase II (rpb2), six new genera, Fragifomes, Niveoporofomes, Piptoporellus, Rhodofomitopsis, Rubellofomes and Ungulidaedalea are established. Four new species, Buglossoporus eucalypticola, Daedalea allantoidea, Piptoporellus hainanensis and P. triqueter are descibed from China. Illustrated descriptions of the novel species are provided. Identification keys to Fomitopsis and its related genera, as well as keys to the species of each genus are provided.
