Description: Thallus subfoliose to squamulose, slightly gelatinous when wet, forming 3-8 cm wide patches, the lobes flattened, slightly undulating over the substrate, 2-7 mm wide, 54-115 µm thick, with entire to poorly lacerate margins. Upper surface with a few ridges to wrinkled, greenish grey to brown, always matt; lower surface with a few, thin, simple hairs towards the base of lobes. Upper and lower pseudocortex poorly developed, consisting of a single layer of irregularly isodiametrical cells, the layer inbetween with loosely interwoven chains of Nostoc and hyphae. Apothecia rather rare and sparse, lecanorine, laminal to marginal, sessile, 0.3-0.8 mm across, with a brown, concave disc and an entire to lobulate thalline margin. Thalline exciple pseudocorticate; proper exciple paraplectenchymatous, 10-12 µm wide laterally; epithecium brownish; hymenium colourless, 180-220 µm high, I+ blue; paraphyses mostly simple, 1-1.5 µm thick at mid-level, the apical cells slightly swollen; hypothecium yellowish to pale orange, 30-55 µm high. 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 submuriform to muriform, hyaline, ellipsoid, (29-)33-43(-52) x (11-)13-17(-19) μm. Photobiont cyanobacterial (Nostoc, the cells in chains). Spot test: all negative. Chemistry: without lichen substances.
