Unreported Endophytic Fungi Isolated from Potato (Solanum tuberosum L.) Leaves in Korea: Didymella sinensis and Sagenomella oligospora

In the present study, we isolated endophytic fungi from the leaves of spring-cultivated potato plants. The fungal strains were identified using the morphological characteristics and molecular analysis of the internal transcribed spacer, large subunit of rDNA, and β-tubulin gene. We confirmed the presence of two endophytic fungal species not previously recorded in Korea: Didymella sinensis and Sagenomella oligospora. Here, we describe the morphological and phylogenetic characteristics of these two fungal species.
