Extract from Wikipedia article: Hydnellum concrescens is an inedible fungus, commonly known as the zoned hydnellum or zoned tooth fungus. As with other tooth fungi, the spores are produced on spines on the underside of the cap, rather than gills. It has a funnel-shaped cap, typically between 2 and 7 cm (0.8–2.8 in) in diameter, which has characteristic concentric zones of color. The cap may also have radial ridges extending from the center to the margins. The spines are pink in young specimens, but turn brown with age.
Hydnellum concrescens is a rare, pinkish-brown to reddish-brown tooth fungus that grows in association with coniferous trees. In St. Petersburg and Leningrad Oblast, it has been found in spruce and pine forests, typically on acidic soils. In north-western Russia, the species is considered endangered due to habitat loss and degradation. Fruitbodies are usually small, 2-5 cm in diameter, with a wavy or lobed cap and crowded, brittle spines. The fungus has been recorded in several nature reserves and protected areas in the region, including the Karelian Isthmus and the Valdai Hills.

Zoned tooth mushrooms (Hydnellum concrescens) between Oselki and Toksovo, north from Saint Petersburg. Russia, August 13, 2024Observations of Hydnellum concrescens in Leningrad Oblast and north-western Russia reveal its presence in various locations near Saint Petersburg. The fungus was found near Kavgolovskoe Lake in Toksovo, Zakhodskoe, Lembolovo, Petiayarvi, Lisiy Nos, Olgino, Kuzmolovo, and between Oselki and Toksovo. It was observed growing alone and with other species, such as Phellodon niger. The sightings occurred over several years, from 2016 to 2024, during the months of July, August, and September. The fungus was found in different habitats, including roadside areas, old railroad grades, and near lakes. The consistent presence of Hydnellum concrescens in these locations suggests that it is a common species in the region. Repeat sightings in the same areas, such as near Kavgolovskoe Lake, indicate that the fungus may be perennial or regularly fruiting in these locations.
