Description: Thallus crustose, episubstratic, effuse, thin, membranous or granulose, pale grey to ash grey, sometimes with a brownish tinge. Apothecia lecideine, sessile, 0.5-1.5 mm across, dark brown to black, sometimes confluent and forming larger tuberculate clusters, with a flat to finally convex disc and a raised, smooth, often flexuose, finally sometimes excluded proper margin. Proper exciple dark reddish brown, K-; epithecium pale brown, reddish brown or almost colourless; hymenium colourless, amyloid, 60-70 µm high, with scattered blue-violet (K+ green) granules which are often present also in the upper part of hypothecium; paraphyses mostly simple, coherent, 1.5-1.7 µm thick at base, the apical cells gradually widening up to 2.5 µm; hypothecium dark reddish brown. Asci 8-spored, clavate, with a I+ blue tholus and an internal, darker I+ tubular structure, the external gel I+ faintly blue, Porpidia-type. Ascospores 0-1(-3)-septate, hyaline, ellipsoid, 9-17(-19) x (3-)4-6(-7) µm, with a finely warted epispore. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV+ white. Chemistry: without lichen substances.
Note: a cool-temperate to arctic-alpine, probably circumpolar lichen found on mosses, plant debris, soil, bark and lignum, especially in upland areas with calcareous substrata.
