This research describes two new species of mushrooms found in southern China and revises their classification within the genus Gymnopus. The study combines detailed physical examination of the mushrooms with DNA analysis to understand their relationships to other species. This work helps scientists better understand fungal diversity and classification. Impacts on everyday life: • Contributes to our understanding of global biodiversity • Helps identify and catalog new species in China’s forests • Improves scientific classification systems used by researchers and naturalists • Aids in the documentation and preservation of natural heritage • Could lead to discovery of useful compounds or properties in these fungi
