This research describes a new species of fungus found growing on submerged bamboo in China and reorganizes the classification of related fungi based on DNA analysis. The findings help scientists better understand the diversity and relationships of fungi that live in freshwater environments. Impacts on everyday life: • Helps track and monitor fungal biodiversity in aquatic ecosystems • Contributes to understanding decomposition processes in freshwater environments • Advances scientific knowledge of fungal taxonomy and classification • Provides baseline data for potential future applications in biotechnology • Aids in assessing environmental health through fungal biodiversity studies
