Taxonomic Re-evaluation of Megacollybia Species in Korea

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.

A Checklist of the Basidiomycetous Macrofungi and a Record of Five New Species from Mt. Oseo in Korea

Basidiomycetous macrofungi play important roles in maintaining forest ecosystems via carbon cycling and the mobilization of nitrogen and phosphorus. To understand the impact of human activity on macrofungi, an ongoing project at the Korea National Arboretum is focused on surveying the macrofungi in unexploited areas. Mt. Oseo was targeted in this survey because the number of visitors to this destination has been steadily increasing, and management and conservation plans for this destination are urgently required. Through 5 field surveys of Mt. Oseo from April to October 2012, 116 specimens of basidiomycetous macrofungi were collected and classified. The specimens were identified to the species level by analyzing their morphological characteristics and their DNA sequence data. A total of 80 species belonging to 57 genera and 25 families were identified. To the best of our knowledge, this is the first study to identify five of these species-Artomyces microsporus, Hymenopellis raphanipes, Pholiota abietis, Phylloporus brunneiceps, and Sirobasidium magnum-in Korea.

Tectella patellaris from Korea

One rare and interesting species collected from Gyeryong-san, Chungnam Province is described and illustrated in detail. The species "Tectella patellaris (Fr.) Murr." and genus "Tectella Earle" is a first record for Korean fungal flora. Specimens cited here have been deposited in the Herbarium Conservation Center of National Academy of Agricultural Sciences.

Taxonomic study on Korean Aphyllophorales (5) - on some unrecorded genera and species -

A total of 149 species and 209 strains of Korean Aphyllophorales in Seoul National University Fungus Collection (SFC) were analyzed by taxonomic and phylogenetic methods. Among those examined fungal specimens, 9 genera Abundisporus, Antrodiella, Cyphellopsis, Dendrothele, Dichomitus, Laxitextum, Piloderma, Skeletocutis and Tubulicrinis, and 23 species, Abundisporus fuscopurpureus, Antrodiella semisupina, Auriporia pileata, Cantharellus subalbidus, Clavulina cinerea, Cyphellopsis confusa, Dendrothele acerina, Dichomitus campestris, Haplotrichum aureum, Heterobasidion annosum, Hyphoderma argillaceum, Hyphodontia tropica, Inonotus dryophilus, Ischnoderma benzoinum, Laxitextum bicolor, Phanerochaete radicata, Phellinus lonicericola, Piloderma byssinum, Skeletocutis nivea, Tomentella terrestris, Trametes elegans, Trametes tenuis, and Tubulicrinis accedens were confirmed as new to Korea and registered here with descriptions.

Unrecorded Higher Fungi of the Songnisan Nation al Park

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.

Taxonomic Studies on the Genus Crepidotus in Korea

For investigation of the species diversity of the Genus Crepidotus in Korea and constructing a key to Korean Crepidotus species, a total of 65 specimens, collected from 18 locations from 1982 to 2002, were observed for morphological characters of carpophores and other features. All the specimens have been preserved in the herbarium of the National Institute of Agricultural Sciences and Technology, R.D.A., Suwon, Korea. The specimens were identified according to the classification systems given by Hesler and Smith(1965), Nordstein(1990), Orton(1960), Pilat(1948), Senn-Irlet(1991, 1992, 1993) and Singer(1951, 1973, 1986). In this study, a total of 10 Crepidotus species were confirmed. Among them, Korean common names were designated to six unrecorded species as follows: C. uber; C. hygrophanus; C. latifolius; C. obscurus; C. subverrucisporus; and C. circinatus. A key to 10 Crepidotus species has been constructed.

The Aphyllophorales of the Kyeryoungsan National Park

Through seven field surveys to the Kyeryoungsan National Park from July to December of the year 2001, 116 specimens of the Aphyllophorales were collected and taxonomically examined. All the specimens were identified to the species by observation of morphological and microscopic characters, along with old specimens from the Kyeryoungsan National Park of SFC herbarium. They amounted to 10 families, 37 genera and 52 species, and two species among them, Antrodia xantha and Ceriporia viridans, were confirmed as new to Korea and are described here as unrecorded species.

The Aphyllophorales of Mungyong Saejae

To evaluate the establishment of Mungyong Saejae Natural Ecology Park located in the northwestern Gyongbuk Province, a scientific survey for the mushroom flora of the park was carried out from May to December of 1999. A checklist of the Aphyllophorales collected from the park was prepared. The list included 67 species of 44 genera belonging to nine families in the Aphyllophorales. Among them, seven species, Antrodia malicola, Ceriporia purpurea, Oligoporus leucospongia, Perenniporia tephropora, Phanerochaete xerophila, Sistotrema diademiferum and Vuilleminia comedens, were confirmed as new to Korea and are registered here as unrecorded species along with descriptions and microscopic drawings.
