Research on the Hwasun Gotjawal Mushroom Species Diversity

This study was conducted to provide the academic foundation for the mushroom species diversity studies on Hwasun Gotjawal, which has not been investigated compared to other Gotjawal in Jeju Island. It was performed for 8 months from April to November 2020, and a total of 16 investigations were performed twice a month. Mushrooms collected through the investigations were identified through the macroscopic characteristics and nucleotide sequencse analysis of the nuclear ribosome ITS region. As a result of the investigation, a total of 17 families, 25 genera, and 33 species of mushrooms were investigated. When examining the pattern of occurrence by family, the Polyporaceae accounted for the largest proportion with 7 species, followed by Hymenogastraceae with 3 species. In this investigation, no climate-sensitive biological indicator species were observed, and 10 biological resources that need to approve for overseas export were observed. In addition, Flammulina filiformis, which has not been officially reported in South Korea, was also observed. In this study, we described the morphological characteristics and phylogenetic tree analysis results and suggest the korean name of the mushrooms.
