The Wood-rotting Fungal Flora of Three Islands in the Yellow Sea, Korea

The wood-rotting fungi of three Korean islands in the Yellow Sea, Soyeonpyung-do (SY), Oeyeon-do (OY), and Gageo-do (GG), were investigated from October 2004 to November 2005. During four sampling trips on each island, a total of 46, 44, and 44 specimens were collected from SY, OY, and GG, respectively. The identified wood-rotting fungi from SY included 29 species of 22 genera and nine families; OY had 31 species of 26 genera and 10 families; and GG had 34 species of 27 genera and 11 families. The majority of the fungi were in the Polyporaceae, which was represented by 23 genera and 30 species. Auricularia polytricha, Daedaleopsis tricolor, Daldinia concentrica, Hymenochaete cinnamomea, Hymenochaete yasudai, Hyphoderma setigerum, Lopharia mirabilis, Schizopora paradoxa, and Trametes versicolor were collected from all three islands.

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.

Wood-rotting Fungal Flora of Kanghwa Island

Through ten field surveys in Kanghwa Island from August of 1997 to March of 2002, total 107 specimens of wood-rotting fungi belonging to the Aphyllophorales were collected and identified to the species. They taxonomically amounted to 10 families, 31 genera, and 48 species. Among them, one family, Steccherinaceae, and four genera, Australohydnum, Castanoporus, Dacryobolus and Haplotrichum were confirmed as new to Korea. Five unrecorded species, Australohydnum dregeanum, Castanoporus castaneus, Dacryobolus karstenii, Haplotrichum conspersum and Hyphoderma odontiiforme were 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.

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.

Phylogenetic Relationships of the Polyporaceae Based on Gene Sequences of Nuclear Small Subunit Ribosomal RNAs

The Polyporaceae is a chaotic mass of genera having poroid hymenophores in the Aphyllophorales. To classify the Polyporaceae into more natural groups, phylogenetic analyses were performed using nuclear small subunit ribosomal DNA sequences. Thirty-six species from the families of the Polyporaceae, the Hymenochaetaceae, the Ganodermataceae, the Corticiaceae, the Bondarzewiaceae, the Meruliaceae, the Steccherinaceae and the Lentinaceae were phylogenetically compared. By performing maximum parsimony analysis, seven phylogenetically meaningful groups were identified and discussed. The hyphal system, presence or absence of clamps, and the type of rot were found as important characters in defining the groups. Each group was phylogenetically significant enough to be a core member of each family when the Polyporaceae was split into smaller and more natural families.

Taxonomic Study on Korean Schizopora

Schizopora paradoxa is a white rot fungus showing great variation in hymenophoral configuration. It has been often treated as close to Irpex or Hyphodontia and frequently confused with S. flavipora which was identified as an unrecorded species in Korea. Distinct features including sizes of basidia and basidiospores as well as hymenophoral shape make S. paradoxa differ from S. flavipora. Remarkable characters of hymenophores and microscopic structures are described and their significance is discussed for the taxonomy of Korean Schizopora.

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.
