Description: Thallus non-lichenized, indistinct, immersed in the thalli of species of the Lecanora polytropa-group. Apothecia biatorine, 0.2-0.3 mm across, black, somehow glossy, sessile, often clustered, with a strongly convex disc, without a distinct proper margin. Proper exciple strongly reduced; epithecium bluish green-black, sometimes in part brown, N+ violet; hymenium colourless, 40-50 µm high; paraphyses coherent, strongly swollen in water, 4-5.5 µm thick at base, the apical cells 5-8 µm wide; hypothecium colourless in upper part, pale yellow-brown in lower part. Asci (4-)8-spored, clavate, the K/I+ blue tholus penetrated by a faintly amyloid apical cushion with parallel or diverging flanks, the outer wall very thin, K/I-, surrounded by a K/I+ blue outer layer, Lecanora-type. Ascospores 1-celled (rarely 1-septate), hyaline, fusiform to bacilliform with rounded ends, 8-12 x (2-)3-4.5 µm. Photobiont absent. Spot tests: all negative. Chemistry: without lichen substances.
