Description: Thallus subfoliose to squamulose, gelatinous when wet, rigid, forming firmly attached, irregular,1-5 cm wide, irregular rosettes. Lobes rounded, 150-350 µm thick, strongly swelling when wet, 1-3 mm wide, with ascending, twisted, often divided and pleated margins, dark brown-black with a reddish or olive tinge, uneven, matt, often ridged, sometimes with coarse, clustered, isidia-like warts. Lower surface paler brown, wrinkled, with scattered tufts of white hapters. Upper and lower cortices poorly developed, consisting of an up to 4 µm thick, single layer of irregularly isodiametrical cells, the layer inbetween with loosely interwoven chains of Nostoc and hyphae. Apothecia rather rare, lecanorine, laminal to marginal, sessile, 0.5-1.5 mm wide, with a brown, concave to flat disc and an entire, raised thalline margin. Proper exciple euparaplectenchymatous, 55-90 µm wide laterally; epithecium brownish; hymenium colourless, 135-160 µm high, I+ blue; paraphyses mostly simple, c. 1 µm thick at mid-level, the apical cells slightly swollen; hypothecium colourless to pale yellow, 50-60 µm high. Asci 8-spored, narrowly clavate, the apex strongly thickened, the apical dome K/I+ pale blue, with a downwardly projecting K/I+ deep blue tubular structure. Ascospores submuriform, with 3 transverse septa and 1 longitudinal septum, hyaline, ellipsoid to subfusiform, (18-)20-28(-35) x (7-)8-16 µm. Photobiont cyanobacterial (Nostoc, the cells in short chains). Spot test: all negative. Chemistry: without lichen substances. Note: a mainly mild-temperate to Mediterranean lichen found on steeply inclined, but not fully sun-exposed seepage tracks of more or less calcareous rocks.
