Three new species of Phanerochaete (Polyporales, Basidiomycota)

Phanerochaetecanobrunnea, P.cystidiata and P.fusca are presented as new species, supported by morphological studies and two sets of phylogenetic analyses. The 5.8S+nuc 28S+rpb1 dataset shows the generic placement of the three species within the phlebioid clade of Polyporales. The ITS+nuc 28S dataset displays relationships for the new taxa within Phanerochaete s.s. Phanerochaetecanobrunnea grew on angiosperm branches in subtropical Taiwan and is characterised by greyish brown hymenial surface, brown generative hyphae and skeletal hyphae and absence of cystidia. Phanerochaetecystidiata grew on angiosperm branches above 1000 m in montane Taiwan and SW Yunnan Province of China and is characterised by cream to yellowish hymenial surface and more or less encrusted leptocystidia. Phanerochaetefusca grew on angiosperm branches at 1700 m in Hubei Province of China and is characterised by dark brown hymenial surface, leptocystidia, brown subicular hyphae and colourless to brownish basidiospores.
