Fruiting bodies are 3 to 16 mm wide and nearly globose. They are grayish-white at first, then becoming pinkish and then brick-red at maturity and finally brownish-black when overmature. The surface is bumpy (pimpled) at maturity. The interior flesh is black and hard.
Grows in clusters on the bark of dead beech trees. Fruiting bodies can last thru the winter.
