Hymenochaetaceae (Basidiomycota) in China

An account of the Chinese species of Hymenochaetaceae based on most recent phylogenetic analysis is presented. One hundred and seventy species from 23 genera are recognized; descriptions are provided based on the Chinese collections. Keys to genera and species are given. Phellinopsis gen. nov. is introduced. Coltricia abieticola sp. nov., Coltricia crassa sp. nov., Coltricia macropora sp. nov., Coltricia spina sp. nov., Coltriciella subglobosa sp. nov., Fuscoporia yunnanensis sp. nov. and Inonotus magnisetus sp. nov. are described here as new. Eighteen new combinations, Fulvifomes cesatii, F. chinensis, F. collinus, F. glaucescens, F. inermis, F. johnsonianus, F. kanehirae, F. macgregorii, F. minisporus, F. pullus, F. umbrinellus, Fuscoporia setifera, Inonotus lonicericola, I. tricolor, Phellinopsis conchata, P. occidentalis, Porodaedalea himalayensis and P. yamanoi are proposed. The taxonomy of all species is discussed. Spore dimensions given in this study derive from at least 30 spores of each species, and 10 386 spores were measured from 347 specimens. Two thousand specimens were examined, and they are listed after each species. Colour photos for 140 species are supplied.This report provides a modern treatment of the Hymenochaetaceae of China. To further support the results of morphology, nuclear large subunit (nuc-LSU) sequences from some typical species were selected to reconstruct their phylogeny.
