Description: Thallus crustose, thinly episubstratic, yellowish grey to grey-green, continuous or more or less granular-warted, forming up to 1(-2) cm wide, orbicular to ellipsoid patches, sorediate, without a distinct prothallus. Soralia yellowish green, partly discrete, punctiform and up to 0.2 mm in diam., partly confluent and convex; soredia farinose, up to 20(-25) μm in diam. Apothecia very rare, biatorine, 0.15-0.3 mm across, pale brown to black, greenish in shade forms, sessile, with a flat to convex disc, soon immarginate. Epithecium more or less blue-green (K-, N+ purple), olive-brown (K-, N-), or a mixture of both; hymenium colourless, 40-55 μm high; paraphyses 1.5-2 μm thick at mid-level, much branched and anastomosing, the apical cells more or less clavate, up to 3 μm wide; hypothecium colourless. Asci 8-spored, broadly clavate, surrounded by a gelatinous, amyloid sheet, with a well-developed, amyloid tholus containing a widely cylindrical axial body and a poorly developed, bluntly conical ocular chamber, more or less Lecanora-type, with spirally arranged spores. Ascospores 3-7-septate, strongly curved and mostly S-shaped, (20-)25-35(-40) x 2-3(-3.5) μm. Photobiont chlorococcoid. Spot tests: soralia K-, C+ fleeting and faintly pink, KC+ fleeting and faintly pink (reactions often visible only in squash preparations!), P-, UV-. Chemistry: gyrophoric acid (traces).
