Three new species of Cyanosporus (Polyporales, Basidiomycota) from China

<i>Cyanosporus</i> is a cosmopolitan genus characterized by effused-reflexed to pileate basidiomata with a bluish tint and allantoid to cylindrical basidiospores which are negative to weakly positive in Melzer's reagent and Cotton Blue, causing a brown rot. Three new species of <i>Cyanosporus</i>, namely, <i>C.linzhiensis</i>, <i>C.miscanthi</i> and <i>C.tabuliformis</i> are described and illustrated. Phylogenies on <i>Cyanosporus</i> are reconstructed with seven loci DNA sequences including ITS, nLSU, nSSU, mtSSU, RPB1, RPB2 and TEF1 based on phylogenetic analyses combined with morphological examination. The description for the new species is given. The main morphological characteristics of all 38 accepted species in <i>Cyanosporus</i> are summarized.
