Description: Thallus small-foliose to subsquamulose, homoiomerous, gelatinous and 150-550 µm thick when wet, forming 5-10(-16) mm wide cushions. Lobes few, 0.5-1.5(-2) mm wide, flattened, adpressed to erect, usually branched, distinctly swollen, sometimes with adventive lobules. Upper surface dark olive-green to brown or black, dull, epruinose, without isidia; lower surface usually paler bluish grey, with scattered white hapters. Upper and lower cortices absent. Apothecia common, lecanorine, numerous and crowded on lobe margins or terminal and often hiding the lobes, sessile and constricted at base, 0.5-1(-2) mm across, with a concave to flat, dark reddish brown disc and a rather thick, but finally often excluded, entire, smooth thalline margin. Thalline exciple ecorticate; proper exciple euthyplectenchymatous; epithecium brownish; hymenium colourless, 85-105 µm high, I+ blue; paraphyses simple or sparingly branched, 2-3 µm thick at mid-level, the apical cells clavate, up to 4.5 µm wide; hypothecium yellowish. Asci 8-spored, cylindrical-clavate, the apex strongly thickened, the apical dome K/I+ pale blue, with a downwardly projecting K/I+ deep blue tubular structure. Ascospores 3-septate, hyaline, oblong or ovoid with usually rounded ends, sometimes slightly constricted at septa, (14.5-)17-24 x 6-8.5 µm. Pycnidia common, mostly marginal, immersed, globose, paler than thallus. Conidia bacilliform, slightly swollen at both ends, 4.5-5 x c. 1 µm. Photobiont cyanobacterial (Nostoc, the cells in long chains). Spot tests: all negative. Chemistry: without lichen substances.
