The first report of two species of Polyporus (Polyporaceae, Basidiomycota) from South Korea

Based on morphological examination, two species of Polyporus , P. dictyopus , and P. tuberaster , were identified, which constitutes the first record of these species in South Korea. To confirm their affinity within the genus Polyporus , the phylogenetic relationships of Polyporus and allied genera were established from nuclear large subunit ribosomal DNA (nLSU rDNA) sequences, and a morphological diagnostic key is presented to clarify the Korean species of Polyporus .
