Description: Thallus crustose, episubstratic, rather thin, smooth, rimose-areolate or areolate, sometimes delimited by a dark prothallus, the areoles up to 0.3-0.6 mm wide, flat, whitish, pale to dark grey or ochraceous, dull. Apothecia at first lecanorine and more or less immersed in thallus, becoming pseudolecanorine and adnate, 0.35-0.8 mm across, with a brown to black-brown (reddish brown when wet), usually flat disc, an entire, finally excluded thalline margin and a dark brown to black, persistent proper margin. Thalline exciple 40-60 µm wide, corticate; proper exciple colourless or more often with a blue-green pigment reacting K+ red and N+ reddish in outer part, c. 10 µm wide, expanding to c. 30 µm wide in upper part; epithecium pale brown, K-; hymenium colourless, 70-110 µm high; paraphyses 2-3 µm wide at base, the apical cells 4.5-6.5 µm wide; hypothecium colourless, 40-100 µm high. Asci 8-spored, clavate, intermediate between the Lecanora- and the Bacidia-type. Ascospores 1-septate, brown, broadly ellipsoid, (17-)19-23(-26) x (9-)10-13(-14) µm, Mischoblastia-type, rarely swollen at septum, the torus poorly developed, the walls lightly pigmented, faintly warted, with an ontogeny of type A (apical wall thickening after septum formation). Pycnidia dark, immersed. Conidia bacilliform, 3-5 x 1-1.5 µm. Photobiont chlorococcoid. Spot tests: K+ yellow, C-, KC-, P+ faintly yellow. Chemistry: cortex with atranorin.
