02Description

Species Profile

Species profile data sourced from the IUCN Red List of Threatened Species.

The Shiner Milkcap faces severe threats from habitat loss due to deforestation and forest fragmentation, which destroys the specific mycorrhizal relationships essential for its survival. Climate change is altering forest conditions and disrupting the delicate ecological balance required for this fungus to fruit and reproduce. Conservation status may vary by region or assessment authority, but declining populations reflect the vulnerability of specialized forest fungi to environmental changes.

Key Facts
