Upper surface creamish or whitish to pale olive-brown, matt, epruinose, without soredia, centrally cracked or indistinctly areolate, pitted-punctate with minute pock-like depressions resulting from abrasion of isidia. Isidia terete, simple, 0.1 mm diam., subglobose, often crowded centrally. Cephalodia sessile, scattered, flattened orbicular, or depressed convex, 0.8-5.0 mm diam., radially folded and wrinkled or cracked, yellowish-brown or pinkish, matt. Apothecia scattered, rotund, subpedicellate 0.5-1.5 mm diam., thalline margin prominent, entire or subcrenulate, proper margin thin, flesh-coloured, disc plane or subconvex, pale pink to dark red or brownish matt, white pruinose. Hymenium 90-150(-180) µm tall, pale yellowish. Hypothecium colourless. Ascospores ellipsoid 12-16.5 × 6-9 µm. Pycnidia immersed, forming minute swellings with punctiform brownish ostioles.
