Diversity of wood rotting fungi within Polyporales: implications from Korean materials.

Recently, molecular studies employing multi-gene datasets elucidated the phylogenetic diversity of Polyporales. Thirty-four valid families are now placed in Polyporales. Although the broad phylogenetic classification of Polyporales was given in 2013, East Asia samples were limited. Our goal was to study the relationship of Korean Polyporales in relation to global diversity. In Korea, 299 species in 106 genera have been recorded in the order Polyporales. In this study, we targeted the order Meruliaceae, using three loci (ITS, rLSU and rpb2) for single and multigene phylogenetic analyses. For the 414 specimens, we identified 32 species in 11 genera. At the genus level, relationships mostly matched previous results, with Bjerkandera, Cystidiophorus, Irpex, Merulius and Phlebia in the plebioid clade and Hyphoderma, Hypochnicium, Junghuhnia, Loweomyces, Radulodon and Steccherinum in the residual polyporoid clade. However, our Hyphoderma samples were not monophyletic, highlighting the need for reclassification. At the species level, some Korean species clustered with their European/North American conspecifics, as expected based on similar morphology, but 11 species did not and may represent new species.
