  • Fungi that infect mushrooms and cause diseases are called mycoparasitic fungi. Understanding the diversity of mycoparasitic fungi in wild mushrooms is important for the mushroom industry, as they can parasitize cultivated mushrooms. However, few studies have been conducted on the diversity of mycoparasitic fungi in wild mushrooms in South Korea. Upon surveying mushroom flora, we found a mycoparasitic fungus and analyzed its strain using molecular phylogeny and morphological examination. The strain was identified as Sepedonium laevigatum, which is an unrecorded species in South Korea. In this study, we described the cultural and microscopic characteristics of this strain of fungus.

  • The importance of utilizing biological resources has become magnified and it has been a big issue to share the benefit among nations as Nagoya Protocol began in 2010. This study was conducted to research the diversity and distribution of wild mushrooms, and to survey the traditional mushroom knowledge of the people in Jejudo which is a volcanic island having a distinctive climate and forest environment. The research sites were Dongbaekdongsan, Keuneonggot, Hallasan National Park, Muryeongarioreum, Saryeonisupgil and other important area where mushrooms are growing spontainously in Jejudo. A total of 511 species comprising 2 phylums, 8 classes, 20 orders and 74 genera were identified from 1600 specimens collected from 2006 to 2012. In previous studies, a total of 561 species comprising 69 families and 99 genera were investigated. As a result, a total of 755 species comprising 23 orders, 87 families and 263 genera were documented in Jejudo. In this study, 137 species were newly identified as unrecorded species in Jejudo and 9 species, Amanita gemmata, Tricholoma aurantiipes, Panellus violaceofulvus, Leucopaxillus septentrionalis, Bondarzewia montana, Psilocybe argentipes, Boedijnopeziza insititia, Sarcoscypha occidentalis for. occidentalis and Morchella patula var. semilibera were the first record for Korea. Also, 7 species, Amanita gemmata, Tricoloma aurantiipes, Panellus violaceofulvus, Leucopaxillus septentrionalis, Boedijnopeziza insititia, Sarcoscypha occidentalis for. occidentalis and Morchella patula var. semilibera were known as only growing in Jejudo. The traditional knowledge was collected from visiting and questionnaire survey in 50 villages in Jejudo. A total of 23 mushrooms were found in which 12 species were used for food, 2 species were poisonous, 6 species were medicinal, 2 species were used for folk religion and 3 species were used for play purposes. Macrolepiota procera was the most commonly used as an edible mushroom and Chlorophyllum neomastoidea was the most well known poisonous mushroom. Also, 267 cases of traditional knowledge about using mushrooms as a food and medicine were collected. This study has significance for supplementing previous studies about distribution of wild mushrooms in Jejudo and documenting unrecorded species in Korea. Also, it is valuable by providing important data of traditional knowledge for using mushrooms since old times.

  • 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.

  • The mushrooms of this study were collected mainly on Mt. Halla on Cheju-do from April of 1995 to October of 1997. A total of 292 species from 127 genera were identified. Among them, 103 species from 41 genera of the Basidiomycota and 88 species from 13 genera of the Ascomycota were recorded for the first time on Cheju-do. Five species were recorded for the first time in Korea. They are: Typhula phacorriza, Cordyceps crinalis, Cordyceps cochlidiicola, Cordyceps longissima and Cordyceps prolifica.

  • Indigenous fungi from Mount Sohwangbyeongsan, Odaesan National Park, Pyeongchanggun, Gangwon-do, South Korea, were investigated between 2013 and 2016. Our survey identified a total of 137 macrofungi species. These species were systematically categorized into 2 phyla, 4 classes, 15 orders, 41 families, and 73 genera. We identified collected specimens to the species level based on their morphology and rDNA sequences. Two species-Lentinellus flabelliformis and Tricholoma stans were newly recorded as macromycota in Korea.

  • In this study, we report the occurrence of four domestic mushrooms (among 317 samples) that were previously undocumented in the eastern part of Jeju Island in Korea. To identify the mushrooms, DNA sequences of the mushrooms were analyzed by comparing them with the data available in NCBI GenBank. Mushrooms were identified as Agaricus flocculosipes, Amanita concentrica, Coprinopsis strossmayeri, and Favolus acervatus, none of which have been previously documented in Korea. Furthermore, microscopic observations revealed that the morphology of the four mushrooms was consistent with the features of the species matched by the DNA sequences analysis.

  • To understand microorganism effects on wild mushroom fruiting bodies, we investigated the fungi in hyphosphere soil supporting wild mushroom species Cortinarius violaceus, Amanita hemibapha, Laccaria vinacelavellanea, and Amanita verna found in the Gotjawal area of Jeju Island. Fungal species identification based on morphological traits and molecular analysis of ITS, LSU rDNA, and β-tubulin gene sequences resulted in isolation and identification of eleven fungal species previously unrecorded in Korea. These newly-recorded species are: Arthrinium kogelbergensis, Kalmusia longisporum, Keithomyces carneum, Neopyrenochaeta cercidis, Penicillium ranomafanaense, Phomatodes nebulosa, Pyrenochaeta nobilis, Tolypocladium album, Talaromyces kendrickii, Talaromyces qii, and Umbelopsis gibberispora, and their morphological characteristics and phylogenetic positions are described.

  • Fresh mushrooms were collected during survey field trips to the southern areas of Songnisan National Park for 24 days from April to November in 2002. Through this investigation, a total of 682 fungal collections were obtained and taxonomically amounted to 5 classes, 14 orders, 44 families and 202 species. Among them, six genera Diplomitoporus, Heterochaete, Hydnochaete, Loweporus, Scytinostroma and Tomentellina, and twelve species, Asterostroma cervicolor, Diplomitoporus crustulinus, Fomitopsts cajanderi, Heterochaete delicate, Hydnochaete tabacinoides, Hyphodontia sambuci, Hypoxylon deustum, Lopharia cinerascens, Loweporus roseoalbus, Phanerochaete chrysosporium, Scytinostroma odoratum and Tomentellina fibrosa were confirmed as new to Korea and registered here with descriptions.

  • Daecheongdo and Socheongdo Islands are located in the West Sea of Korea, 210 km away from land, and are military border areas very close to North Korea, making them difficult to access. Although the ecosystem of the islands is relatively well preserved due to the lack of accessibility, research on fungi of the regions is insufficient. Therefore, we aimed to investigate indigenous fungi in these geographically and geopolitically constrained regions. A survey of the indigenous fungal diversity of the islands was conducted in 2018. All specimens were identified at the species level based on morphological and molecular analyses. Among them, six macrofungi-namely, Agaricus menieri, Crepidotus praecipuus, Dichomitus squalens, Hortiboletus amygdalinus, Melanoleuca friesii, and Trametes lactinea-were not previously reported in Korea. Considering that the proportion of unrecorded species is high in the survey area and period as well as the number of samples collected, similar research on adjacent islands may be necessary.

  • The indigenous fungi in Mudeungsan National Park were investigated between 2020 and 2022. All collected specimens were identified to the species level based on their morphological characteristics and rDNA sequences. Species belonging to the family Boletaceae were analyzed in depth. Six species, Aureoboletus sinobadius, Hourangia densisquamata, H. nigropunctata, Tengioboletus glutinosus, Tylopilus himalayanus, and Xerocomus subparvus were newly recorded as macromycota in Korea.
