Abstract
We isolated endophytic fungal strains from the roots of three medicinal crops, Ligusticum chuanxiong, Angelica gigas, and Cnidium officinale, cultivated at Yeongju, Korea. The fungal strains were identified based on their morphological characteristics and molecular analyses of their internal transcribed spacer, large subunit rDNA, and beta-tubulin regions. Thereby, we identified three previously unrecorded endophytic fungal species, Dactylonectria pauciseptata, Rhizopycnis vagum, and Sistotrema sernanderi, in Korea. In this report, we describe the morphological characteristics and phylogenetic analyses of these three fungal species.
