Coltricia (Hymenochaetaceae, Basidiomycota) is a genus of terrestrial or wood-inhabiting ECM fungi with a broad range of morphological characters, varying from stipitate, pendant, effused-reflexed to resupinate basidiomes. To address the paraphyletic phylogeny, Coltricia has recently been revised to include the genus Coltriciella, which forms a sister clade with Coltricia and shares similar morphology besides verrucose basidiospores. However, these taxonomic revisions have not yet been reflected in Korea. In this study, we examined 42 specimens initially identified as Coltricia spp. and Coltriciella spp. in Korea. Phylogenetic analysis was performed using four genetic markers (ITS + nrLSU + RPB2 + TEF1) and morphological characters. As a result, nine species of Coltricia were identified, including four new species candidates.
