Note of Five Unrecorded Mushrooms Including Three Rare Species on Mount Juwang in Korea

Abstract

The Mount Juwang was designated as a national park in 1976 because of its unique bedrock geology. Although Juwang National Park has maintained its natural ecosystem well, few macrofungal surveys have been carried out. As a part of a project supported by the National Institute of Biological Resources (NIBR) for the discovery of indigenous fungal species, we surveyed the mushrooms in Juwang National Park from 2018 to 2019. The macrofungi were identified based on morphological and molecular analyses. Among these fungi, five specimens were identified as species previously unrecorded in Korea: Calocybe decolorata , Crepidotus brunnescens , Mycena pearsoniana , Psathyrella phegophila , and P. sulcatotuberculosa . Three of these species are known to be rare in the world: Crepidotus brunnescens , P. phegophila , and P. sulcatotuberculosa . In this study, we provide detailed morphological descriptions of the five unrecorded species from Mt. Juwang in Korea.

Notes of Five Wood-Decaying Fungi from Juwangsan National Park in Korea

“…subsetigerum , and L. orientalis , which were corticioid species. A previous study conducted in Juwangsan focused on unrecorded cap-forming saprobic fungi [ 14 ]; therefore, this is the first study on wood-decaying polyporoid or corticioid fungi in Juwangsan. Studies on polyporoid and corticioid fungi in Korea are relatively scarce, although globally, wood-decaying fungi have been studied intensively for a decade [ 41–47 ].…”

“…We investigated the diversity of macrofungi in Juwangsan National Park from 2018 to 2019 and collected 406 macrofungal specimens during the survey. Consequently, we reported five previously unrecorded species [ 14 ]. Furthermore, we discovered five other species new to Korea.…”
