  • 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.

  • A fungal strain designated KNU-WDM2A2 was isolated from mosquitoes in Gimcheon, Korea. The pure culture was transferred to potato dextrose agar (PDA) and synthetic nutrient agar (SNA) media and attained a diameter of 90 mm after 10 days of incubation at 25℃. The colonies were whitish to light pink and cottony to wooly, with an abundant production of aerial mycelia. The strain produced hyaline to slightly yellowish conidiophores that were rough-walled and branched, with conidiogenous cells arising terminally or laterally. Conidia were unicellular, hyaline to light brown, smooth, and oval or ovoid to clavate, with a size of 4.1-6.9×2.5-3.3 ㎛ (n=65). A phylogenetic analysis was conducted using the internal transcribed spacer (ITS) regions and 28S rDNA of large subunit (LSU) sequences, to support the cultural and morphological characteristics. The KNU-WDM2A2 strain was identified here as Biscogniauxia petrensis, new to Korea.
