Description: Thallus minutely foliose to squamulose, slightly gelatinous when wet, of ascending, crowded lobes, often forming 2-4(-6) cm wide, loose cushions. Lobes grey-brown to dark brown, often paler and bluish grey in the basal, less exposed parts, thin, loosely attached, (0.3-)1-3(-4) mm broad, up to c. 1 cm long, 80-150 µm thick, more or less imbricate, the surface wrinkled, the edges deeply dilacerate-fimbriate, with cylindrical, isidia-like, often dense marginal outgrowths. Lower surface paler, erhizinate, with distinct, raised, longitudinal ribs and scattered white hapters. Upper and lower cortex of a single layer of angular, more or less isodiametrical cells, the layer inbetween of intertwined hyphae and loosely arranged chains of Nostoc. Apothecia rare, lecanorine, strongly constricted at base, 0.3-0.7(-1) mm across, with a brown, slightly concave to flat disc, and a thalline margin often covered in coralloid outgrowths. Proper exciple euparaplectenchymatous, 20-70 µm wide laterally; epithecium brownish; hymenium colourless, 130-200 µm high; paraphyses coherent, mostly simple, 1-1.5 μm thick at mid-level, the apical cells slightly swollen; hypothecium pale yellow, 35-70 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, with 5-9 transverse septa and 1-3-longitudinal septa. thin-walled, hyaline, broadly ellipsoid to subfusiform, (18-)25-40(-50) x 11-16 μm. Photobiont cyanobacterial (Nostoc, the cells in short chains). Spot test: all negative. Chemistry: without lichen substances.
Note: a widespread holarctic lichen mostly found on soil and amongst mosses in dry grasslands, more rarely on basal parts of trunks. Many records could refer to S. pulvinatum (see notes to that species, to S. imbricatum, and to S. gelatinosum).
