Description: Thallus crustose, thin, smooth or finely rimose, grey to almost white, the fertile form grey-ochre, the sterile form more whitish, forming up to 12 cm wide patches. Apothecia lirelliform, confined to restricted areas on the thallus, (0.3-)0.6-1.5(-2.5) x 0.1-0.3 mm, most often simple and isolated, rarely furcate or stellate and arranged in small clusters, half immersed, with a slit-like to slightly expanded disc and a black to slightly grey-pruinose proper margin. Proper exciple black, carbonized, extending below the hymenium, 28–40 µm thick laterally, 40-50 µm thick at base, K-; epithecium brown; hymenium colourless, 50-60 µm high, I+ yellowish; paraphysoids branched and anastomosing, c. 1 µm thick, the apical cells hardly swollen; subhymenium brownish, 10-15 µm high. Asci 8-spored, cylindrical-clavate, the inner layer of the endoascus amyloid throughout, the apical ring hardly visible, Vulgata-type, 40-50 x 12-15 µm. Ascospores 4-7-septate, hyaline, markedly elongate with pointed ends, 15-25(-30) x 3-4(-5) µm, surrounded by a c. 1 µm thick gelatinous perispore. Pycnidia often abundant (in sterile forms), 0.15-0.25 mm in diam., regularly distributed, at first immersed and appearing as pale brown punctiform ostioles, later prominent, appearing as white-pruinose, subglobose, up to 0.4 mm tall warts, the wall K-, N-. Conidia bacilliform, straight or slightly curved, hyaline, 3-7 x 1-1.5 µm. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
