Description: Thallus crustose, white-pruinose, thin and more visible in the wet state, reduced to 3-7 short, whitish grey to greenish grey, broadly triangular lobes radiating all around the apothecia. Lobes composed of branched and partly anastomosing, parallel and more or less radiating hyphae with thin lumina and thick, strongly gelatinized walls. Apothecia frequent, immersed, 0.5-2(-4) mm across, with a brownish black, concave to flat, smooth disc. Proper exciple of branched and anastomosing, radially arranged hyphae; epithecium greenish brown; hymenium colourless, 140-155 µm high, the hymenial gel not amyloid; paraphyses simple, slender, 1-2 µm thick, not apically thickened, free; hypothecium colourless, lying above a layer of algae. Asci 32-64-spored, narrowly clavate, thin-walled except for a slightly thickened apical tholus, K/I-, with a ± small ocular chamber. Ascospores 1-septate (a few rarely up to 3-septate), slightly constricted at septa, hyaline, narrowly ellipsoid to kidney-shaped, (7-)11-17 x (2-)3-4(-7) µm. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
