Taxonomic Revision of the Genus <i>Lactifluus</i> (Russulales, Basidiomycota) of South Korea

Lactifluus (Pers.) Roussel is an ectomycorrhizal genus that was recently recognized to be distinct from the Lactarius. To date, 226 species have been reported worldwide. Misidentification of common because intraspecific morphological variation, cryptic diversity, and limited number taxonomic keys available. Molecular data are indispensable for delimitation; a multilocus phylogenetic analysis showed most Asian not conspecific with morphologically similar present on other continents. In particular, Korea has misused European North American names. this study, we evaluated taxonomy in using both molecular (ITS, nrLSU, rpb1, rpb2) data. We examined 199 specimens collected between 1980 2016, total 24 across four subgenera were identified. All Korean clearly separated species. Five taxa corresponded previously described Asia remaining 19 confirmed as new Herein, provide within their subgenera, phylogenies, summary detailed description
