Extract from Wikipedia article: Hydnellum aurantiacum is an inedible fungus, commonly known as the orange spine or orange Hydnellum for its reddish orange or rusty red colored fruit bodies. Like other tooth fungi, it bears a layer of spines rather than gills on the underside of the cap. Due to substantial declines in sightings, this species is listed as critically endangered in the United Kingdom.

AI-generated description

Hydnellum aurantiacum is a rare, orange to reddish-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 association with mosses and lichens. In north-western Russia, it is considered a endangered species due to habitat destruction and fragmentation. Fruit bodies are typically small, 2-6 cm in diameter, with spines 2-5 mm long, and appear in late summer to early fall.
