In this study, roots of Epipactis thunbergii were collected from Chujado on the north of Jeju-do. Six fungal isolates were isolated from surface-sterilized roots of the orchid and classified with groups based on morphological characteristics. Fungal DNA was extracted from each isolate and amplified ITS region using ITS1-OF/ITS4-OF primer pair. Three species of orchid mycorrhizal fungi were identified as Tulasnella calospora, Tulasnella sp. and Sebacina sp. based on molecular and morphological characteristics.

This study was performed to isolate and identify the orchid mycorrhizal fungi (OMF) from roots of five species of terrestrial orchids in Korea; Cymbidium goeringii, Spiranthes sinensis, Calanthe discolor, Bletilla striata, Pogonia minor. DNA was extracted from isolated OMF and ITS region was amplified using primers, ITS1-OF and ITS4-OF. Four species of OMF belong to Tulasnellaceae and Sebacinaceae were identified; Tulasnella calospora, Tulasnella irregularis, Tulasnella sp., Sebacina vermifera.

Higher Fungi were collected. twice a month from May to September 2004 during field survey trips to Seoraksan and Odaesan National Parks. All the collected specimens were investigated for the morphological characters of carpophores and other features, and deposited in the herbarium of the Entomopathogenic Fungal Culture Collection (EFCC), Kangwon National University, Chuncheon. Among the identified specimens, three genera Rhodotus, Hotermannia and Sebacina and four species Rhodotus palmatus, Gomphus clavatus, Holtermannia corniformis and Sebacina incrustans were confirmed as new to Korea and reported here with descriptions.

In this study, we analyzed the diversity of ectomycorrhizal (ECM) fungal communities of Quercus spp. roots in the limestone area. We identified 45 generd of ECM using next generation sequencing (NGS) analysis. Soil chemical composition analysis confirmed soil pH, substitution calcium concentration, total nitrogen content, organic phosphate, and organic matter content. Shannon's Index was calculated according to the changes in soil chemical composition. The results of cluster analysis showed that Sebacina, Tomentella, Tuber, Densospora, Inocybe, Suillus, and Piloderma were the main genera of symbiotic ECM fungi that thrived in soil with high pH and calcium content.

Depending on the mode of nutrition exploitation, major fungal guilds are distinguished as ectomycorrhizal and saprotrophic fungi. It is generally known that diverse environmental factors influence fungal communities; however, it is unclear how fungal communities respond differently to environment factors depend on fungal guilds. In this study, we investigated basidiomycetes communities associated with Quercus mongolica using 454 pyrosequencing. We attempted to detect guild pattern (ectomycorrhizal or saprotrophic fungal communities) by comparing the influence of geography and source (root and surrounding soil). A total of 515 mOTUs were detected from root (321) and soil (394) of Q. mongolica at three sites of Mt. Jeombong in Inje County. We found that patterns of diversity and community structure were different depending on the guilds. In terms of alpha diversity, only ectomycorrhizal fungi showed significant differences between sources. In terms of community structure, however, geography significantly influenced the ectomycorrhizal community, while source appeared to have a greater influence on the saprotrophic community. Therefore, a guildbased view will help to elucidates novel features of the relationship between environmental factors and fungal communities.
