Extract from Wikipedia article: 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.

AI-generated description

Phellodon niger is a rare, blackish-brown tooth fungus that grows on the ground in coniferous forests. In St. Petersburg and Leningrad Oblast, it has been found in pine and spruce forests, typically in areas with acidic soils. In north-western Russia, it is considered a rare species, often associated with old-growth forests and mature trees. Fruit bodies are usually small, 2-6 cm in diameter, with a black to dark brown cap and white to pale yellow teeth. The fungus is saprotrophic, playing a role in decomposing organic matter in the forest ecosystem.

AI-generated summary of observations

Observations of Phellodon niger in Leningrad Oblast and north-western Russia show that the fungus grows in various locations, including forests and roadsides. It was found in Dibuny, Orekhovo, and near Kavgolovskoe Lake in Toksovo, all located north or north-west of Saint Petersburg. The fungus was observed growing alone and in groups, with some observations noting its presence alongside other species, such as Hydnellum concrescens. The observations were made over several years, from 2016 to 2024, with multiple sightings in the same locations, suggesting that Phellodon niger is a relatively common species in the region. The fungus was found growing on the ground, with its underside featuring tooth-like structures, characteristic of the species. Overall, the observations provide insight into the habitat and distribution of Phellodon niger in north-western Russia.
