Description: Thallus crustose, episubstratic, usually <1 mm thick, rimose-areolate, pale to dark grey, without a distinct prothallus. Areoles flat to slightly convex, irregular in outline, 0.3-1(-1.5) mm wide, slightly constricted at base. Apothecia lecanorine, immersed in the areoles, 1-3(-8) per areole, 0.4-0.6 mm across, often angular, linear or deformed, sometimes confluent, with a black, often grey-pruinose disc, and a thin, irregular, not or only slightly raised thalline margin. Epithecium dark brown to blackish brown, K+ deep violet; hymenium colourless; hypothecium colourless or yellowish. Asci 8-spored, , broadly cylindrical, the apex with a broad ocular chamber, the outer sheath K/I+ blue, otherwise K/I-, with an inner extensible layer, Pertusaria-type. Ascospores 1-celled, hyaline, ellipsoid to fusiform, (20-)25-40(-50) x 10-25 µm, the wall smooth, 1-layered, (2-)3-5 µm thick. Pycnidia immersed. Conidia bacilliform, 7-10 µm long. Photobiont chlorococcoid. Spot tests: thallus K- or K+ pale yellow, C-, KC- or KC+ pale yellow, P- or P+ brownish orange, UV-. Chemistry: stictic acid (major), constictic and norstictic acids (both minor).
