Description: Thallus crustose, endosubstratic or thinly episubstratic, continuous to rimose, pale grey or greenish grey. Medullary hyphae I-. Apothecia biatorine, rounded to slightly irregular in outline, rarely tuberculate, adnate to sessile and constricted at base, 0.25-0.7(-1) mm across, with a ochre to reddish brown (in older apothecia sometimes almost black), flat to slightly convex disc and a concolorous or usually slightly darker, soon excluded proper margin. Proper exciple pale brown in outer part, colourless or with small pigmented droplets within, 25-60 µm wide laterally, 35-85 µm wide at base, of radiating hyphae with swollen end cells; epithecium reddish brown, 5-10 µm high, K-; hymenium colourless to pale yellowish brown, 35-55(-70) µm high, I+ blue; paraphyses simple or sparingly branched and anastomosing, 0.7-2 µm thick at mid-level, the apical cells 2.5-5 µm wide, with a brown cap; hypothecium colourless or very pale brown, 45-125(-170) µm high. Asci 8-spored, distinctly thickened at the apex, with a I+ blue tholus, the outer gelatinous coat I+ pale blue, approaching the Bacidia-type. Ascospores 1-celled, hyaline, fusiform, (7-)9-15(-18) x 3-4(-5) µm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
