Hydnellum mirabile is an inedible species of tooth fungus in the family Bankeraceae. It is found in Europe and North America, where it grows on the ground in forested areas. Caps are brownish to dark brown with yellow edges, and have a hairy surface. On the cap underside (the hymenium) hang brownish spines with paler tips. The spores are roughly spherical with tubercles on the surface, and measure 5–7 by 4.5–6 µm.
