Overview
Hydnellum caeruleum, commonly known as the blue-gray hydnellum, blue-green hydnellum, blue spine, blue tooth, or bluish tooth, is an inedible fungus found in North America, Europe, and temperate areas of Asia.
Hydnellum caeruleum, the Blue Tooth fungus, faces severe decline primarily due to habitat loss from deforestation and agricultural conversion of old-growth forests where it forms essential mycorrhizal relationships. Air pollution, particularly nitrogen deposition, disrupts the delicate soil chemistry required for this species' survival. Climate change further threatens its specialized ecological niche by altering temperature and moisture conditions in its forest habitat.
Habitat
Hydnellum caeruleum is mycorrhizal and often found in the humus beneath conifer trees.
H. caeruleum is an ectomycorrhizal fungus native to temperate regions of Asia, Europe, and North America. The species is commonly found in pine and spruce ecosystems due to its mycorrhizal relationships with coniferous trees.
