Overview
Phellodon niger, commonly known as the black tooth, is a species of tooth fungus in the family Bankeraceae, and the type species of the genus Phellodon. It was originally described by Elias Magnus Fries in 1815 as a species of Hydnum. Petter Karsten included it as one of the original three species when he circumscribed Phellodon in 1881.
The fungus is found in Europe and North America, although molecular studies suggest that the North American populations represent a similar but genetically distinct species.
Black Tooth (Phellodon niger) faces significant threats from habitat degradation and loss of old-growth forest ecosystems essential for its mycorrhizal relationships. Climate change and air pollution are altering forest conditions, while logging and development fragment the mature coniferous forests this species depends on for survival.
Habitat
Mature coniferous forests, particularly old-growth stands dominated by pine, fir, and spruce species where it forms essential mycorrhizal associations with tree roots. Typically found in undisturbed forest ecosystems with well-developed soil layers and stable moisture conditions.
