Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
The White Webcap faces severe threats from habitat destruction and degradation of old-growth forests across its limited range. Climate change and increasing forest fragmentation are further reducing suitable habitat for this specialized mycorrhizal fungus, which depends on specific host tree relationships and stable forest ecosystems.
Key Facts
Habitat & Distribution
Mature coniferous and mixed forests, particularly those with established mycorrhizal networks in temperate regions. The species requires stable forest floor conditions with appropriate soil chemistry and long-term associations with specific host trees.
