Abstract

In this study, we isolated endophytic fungal strains from the rhizoid and the leaf of Mnium heterophyllum and Hypnum plumaeforme, respectively. The isolated strains were identified based on morphological characters and molecular analysis of the internal transcribed spacer, large subunit rDNA, β-tubulin, and RNA polymerase II subunit regions. From the results, we confirmed two endophytic fungal species, Cercophora thailandica, and Biscogniauxia petrensis, which to the best of our knowledge, have not yet been reported in Korea. We further describe the morphological characteristics and the results of the molecular analyses of these isolated fungal strains.
