The flesh is thick, white, firm, brittle, and bruises yellow to orange-brown. The underside is densely covered with small, slender off-white to pinkish spines measuring 2–7 mm long. These spines sometimes run down at least one side of the stem. Odor not distinctive. Stem
Thick, central of off center; colored like cap or lighter.
Hydnum albidum has a white cap, smaller spores, and occurs on alkaline soil. Closely related Hydnum refescens is smaller and orange.
