This research documented two previously unknown species of microscopic fungi in Korea. These fungi play important roles as decomposers in natural ecosystems. The study expands our understanding of fungal diversity in Asia. Impacts on everyday life: • Helps track biodiversity changes that could affect ecosystem health • Contributes to understanding decomposition processes in nature • Advances knowledge of Asian fungal species distribution • Supports conservation efforts through better species documentation • Aids in identifying potential new species for biotechnology applications
