Biodiversity Documentation in Northeast India: Discovery of Russula griseopurpurata

The recent identification of the mushroom species *Russula griseopurpurata* in the Ri-Bhoi district of Meghalaya marks a significant addition to India’s mycological records. Discovered in the vicinity of sal (*Shorea robusta*) trees, this species is distinguished by its unique greyish-purple cap. While the discovery was localized to Meghalaya, the species has also been documented in West Bengal, suggesting a broader distribution pattern across the eastern Indian landscape. This discovery underscores the critical importance of the Eastern Himalayas as a global biodiversity hotspot. Fungi play an indispensable role in forest ecosystems, acting as primary decomposers and forming symbiotic mycorrhizal relationships with trees, which are essential for nutrient cycling and forest health. However, fungal diversity in India remains significantly under-documented compared to flora and fauna. The *Russula* genus, known for its diverse species, serves as a vital indicator of forest ecosystem integrity. The presence of such species in regions like Meghalaya highlights the need for intensified taxonomic research and habitat conservation, especially as these areas face increasing pressure from land-use changes and climate-induced shifts in vegetation.
