Extract from Wikipedia article: Phellodon melaleucus, commonly known as the grey tooth, is a species of tooth fungus in the family Bankeraceae. It was originally described by Elias Magnus Fries in 1815 as a species of Hydnum. In 1881, Petter Karsten included it as one of the original three species in his newly circumscribed genus Phellodon. The fungus is widely distributed in Europe and North America, where it associates mycorrhizally with a wide range of host trees. It is considered vulnerable in Switzerland.
