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.

: Orchid mycorrhizal fungi (OMF) were examined in roots of the six terrestrial species of orchids collected in Ulleung Islands. Seven OMF isolates from the roots of orchids were identified based on morphological and molecular characters. Internal transcribed spacer region of OMF DNA was amplified using basidiomycete-specific ITS primers, ITS1-OF and ITS4-OF. OMF beloning to Tulasnellaceae and Ceratobasidaceae was identified through molecular analysis.
