Hydnellum scrobiculatum can be recognized by a fibrillose to pitted-scaly, brown to reddish brown cap with paler, often zonate margin, short buff-brown spines, brown to reddish brown context tissues, and a mild or faintly farinaceous odor and taste. Hydnellum aurantiacum has a more coarsely lumpy-nodulose cap with bright rusty to cinnamon colors and brighter orange to orangish brown context tissues.
