Rosette Tooth
Hydnellum cumulatum
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
The Rosette Tooth faces severe decline due to nitrogen pollution from agricultural runoff and atmospheric deposition, which fundamentally alters soil chemistry in its preferred habitats. Habitat fragmentation from forestry practices and urban development has isolated populations, reducing genetic diversity and limiting spore dispersal. Climate change compounds these pressures by altering precipitation patterns and soil moisture levels critical for this ectomycorrhizal species' survival.
Habitat
Hydnellum cumulatum inhabits mature coniferous and mixed forests, forming ectomycorrhizal associations with pine, spruce, and fir trees in acidic, nutrient-poor soils. The species requires undisturbed forest floors with stable soil chemistry and is particularly sensitive to nitrogen-enriched environments.
