Description: Thallus crustose, endosubstratic, greyish white, mostly inapparent. Apothecia lecideine, 0.7-1 mm across, slightly immersed to subsessile, with a dark brown to black (brown-red when moist), but densely white- to bluish-pruinose, flat to slightly convex disc, and a thin, soon excluded proper margin. Proper exciple 100-150 μm wide, of radiating hyphae with swollen and dark brown tips, the rim dark brown, the inner part pale brown to colourless; epithecium brown; hymenium colourless, 120-150 µm high, the hymenial gel hemiamyloid, K/I+ light blue fading to light red; paraphyses coherent, simple to sparingly branched, regularly septate, 1-1.5 μm thick at mid-level, the apical cells 2-3 μm wide, with dark-pigmented gel caps; hypothecium colourless. Asci >100-spored, cylindrical-clavate, strongly thickened at apex, the apical dome K/I-, the outer coat K/I+ blue. Ascospores 1-celled, hyaline, globose and 3-4 µm wide or broadly ellipsoid and 3-5.5 x 3-4 µm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
