In this study, endophytic fungi were isolated from the roots of three native orchid species from
Korea: Bletilla striata, Oreorchis patens, and Cephalanthera longibracteata. The isolated fungal
endophytes were identified based on the morphological and molecular characteristics including
sequence analysis of internal transcribed spacer (ITS) and 28S ribosomal DNA regions. As a
result, we discovered 5 species of fungal endophytes that have not been previously reported in
Korea: Phialocephala bamuru, Coniochaeta mutabilis, Phialophora foetens, Calonectria
canadensis, and Neonectria ramulariae.
