Summary ²

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.
