Description: Thallus crustose, endosubstratic or thinly episubstratic, yellowish or greenish yellow, sometimes with a brownish hue, continuous to granulose, sometimes forming an areolate crust, the granules contiguous, 0.1-0.2 mm wide, slightly convex. Apothecia lecanorine, sessile, round to irregular in outline, 0.5-1.5(-3) mm across, with a pale yellow-green to pale greenish brown, epruinose, flat to convex disc and a thin, often finally excluded thalline margin. Thalline exciple corticate, with sparse algae, lacking crystals, 30-70 µm wide laterally, up to 110 µm wide at base; proper exciple colourless, 25-50 µm wide; epithecium brownish, without crystals; hymenium colourless, 45-60 µm high, I+ blue; paraphyses coherent, sparingly branched and anastomosing, 1.5-2 µm thick at mid-level, the apical cells up to 2.5 µm wide; hypothecium pale yellowish brown. Asci 8-spored, clavate, Lecanora-type. Ascospores 1-celled, hyaline, narrowly ellipsoid, 7-14 x 2.5-4 µm. Spot tests: thallus K-, C-, KC+ yellowish, P-. Chemistry: isorangiformic acid, usnic acid and zeorin.
