In this study, three fungal isolates belonging to the phylum Ascomycota under classes Leotiomycetes, Eurotiomycetes, and Sordariomycetes were isolated from soil in Korea. These species were designated as KNUF-22-003, KNUF-22-005, and KNUF-20-NI016, respectively, and identified based on their phylogenetic relationships and morphological characteristics. The isolates were confirmed through molecular phylogenetic analyses of their internal transcribed spacer (ITS) region, 28S rDNA large subunit (LSU), and actin (ACT1 ) gene sequences. Cultural and morphological characteristics of strains KNUF-22-003, KNUF-22-005, and KNUF-20-NI016 were matched with Chaetomella oblonga CBS110.78^T, Oidiodendron chlamydosporicum CBS403.69^T, and Sarocladium subulatum CBS217.35^T, respectively. To the best of our knowledge, this is the first report on C. oblonga, O. chlamydosporicum, and S. subulatum in Korea.
