title: Taxonomic Re-evaluation of Megacollybia Species in Korea.
abstract: The diversity of the genus Megacollybia in Korea was examined based on morphological observation and analysis of molecular data. Currently, the genus is consisted of nine species with a global distribution. However, only M. platyphylla has been reported in the floral survey of Korea. During our re-evaluation of the taxonomic diversity of Megacollybia in Korea, six Megacollybia specimens collected in 2012 were identified based on internal transcribed spacer (ITS) sequences and morphology. Here, we report two Megacollybia species, M. clitocyboidea and M. marginata, as newly recorded species from Korea. The microscopic features of the two species are provided in this study. To our knowledge, this is the first phylogenetic analysis of Korean Megacollybia species.
