This research describes a newly discovered mushroom species from Thailand and confirms the presence of a rare mushroom species not seen in the country for nearly a century. The study used both physical characteristics and DNA analysis to identify and classify these fungi. The findings contribute to our understanding of fungal diversity in Southeast Asia. Impacts on everyday life: – Helps scientists track and preserve fungal biodiversity – Contributes to the documentation of Thailand’s natural heritage – Advances our understanding of mushroom evolution and relationships – Provides reference material for future mushroom identification – May lead to discovery of new useful compounds or applications
