Isidia central, sparse to numerous, wrinkled-warted, terete, simple to branched, to 4 mm tall. Cephalodia sparse to numerous, irregularly pulvinate or rounded-cerebriform, to 3 mm diam., pale flesh-coloured, matt, epruinose. Apothecia numerous, scattered, subpedicellate, 2-3 mm diam., thalline margins prominent, entire, subcrenulate, often white-pruinose, disc plane to subconvex, pinkish-brown to brown-black, wrinkled often pruinose. Hymenium 130-140(-160) µm tall, pale brown-yellow at apices. Hypothecium colourless. Paraphyses slightly thickened at apices.
