Taxonomic Re-Evaluation of the Genus Fuscoporia in the Republic of Korea Including Three Unrecorded Species

The genus ( , ) comprises poroid white-rot fungi characterized by dark brown hymenial setae, a dimitic hyphal system, and encrusted generative hyphae. Despite the ecological and commercial significance of species, their identification has been challenging owing to their morphological overlap with other genera of and to the limited resolution of nuclear ribosomal DNA markers. With the advances in molecular research, has been revised to include species from sensu lato and sensu lato, and 71 new species have been reported over the past decade. In Korea, a comprehensive taxonomic study elucidating the true diversity of is yet to be conducted. Among the 11 species reported in Korea, two were identified solely based on morphological characteristics, and four were identified based on nuclear ribosomal DNA regions, which have limited resolution for species identification in . To investigate the current status of species native to Korea, we conducted a phylogenetic study using four genetic markers (ITS + nrLSU + + ), along with morphological characteristics, and re-analyzed the GenBank records deposited from Korea. Ten species were identified, including three previously unrecorded species. A detailed description of the unrecorded species and a list of proposed Korean names for all species in Korea are provided. This study will guide further taxonomic and applied research of by providing a species identification key and a verified multigenetic database, in addition to confirming the sequences in public database.
