Description: Thallus crustose, episubstratic, whitish grey to yellowish white, often becoming pinkish in the herbarium, verrucose-granulose. Areoles strongly convex to globose, contiguous, to 0.3 mm broad, some of them becoming sorediate starting from the top, and forming subtuberculate, 0.5-1.5 mm wide soralia. Soredia granular, whitish to pale ochraceous. Apothecia very rare in Italian material, lecanorine, rounded, sessile, strongly constricted, up to 2.5 mm across, with a reddish brown to almost black, flat, more or less smooth, pruinose disc, and a thick, undulate to crenulated thalline margin. Epithecium reddish brown; hymenium and hypothecium colourless; paraphyses thin, anastomosing, densely branched. Asci 2(-3)-spored, broadly cylindrical. Ascospores 1-celled, hyaline, ellipsoid, 22-40 x 15-20 µm, the wall thick, zoned. Pycnidia dark, immersed. Conidia bacilliform. Photobiont chlorococcoid. Spot tests: K+ yellow, C+ red, KC+ yellow-red, P+ yellow-orange, UV- or UV+ orange. Chemistry: alectorialic and barbatolic acids, plus variable amounts of xanthones.
