Thallus verrucose to verrucose-areolate or subsquamulose, plane to slightly bullate, whitish grey to bluish grey, epruinose or with a thin bluish grey pruina. Soredia absent. Prothallus not visible. Apothecia sessile, 0.9–3.0 mm diam.; disc dark red-brown to ±black, bluish grey-pruinose; margin bluish grey, thin, entire, ±verrucose to crenulate. Cortex indistinct, hyaline, inspersed with numerous small crystals, 30–50 µm thick laterally and 45–75 µm thick basally. Amphithecium with small crystals soluble in KOH (allophana-type). Parathecium hyaline, without crystals, 10–15 µm thick. Epihymenium reddish brown, K–, c. 10–15 µm thick, with numerous small crystals soluble in KOH. Hymenium, subhymenium and hypothecium hyaline.
