This research discovered two new species of fungi and documented another species for the first time in China, all found in freshwater environments. The study helps us better understand the diversity of microscopic fungi that play important roles in decomposing plant material in streams and rivers. Impacts on everyday life: – Helps track biodiversity changes in freshwater ecosystems – Contributes to understanding natural decomposition processes in streams – Advances knowledge of fungal species that could have future applications in biotechnology – Supports water quality monitoring through better understanding of aquatic organisms – Aids conservation efforts by documenting species diversity
