Description: Thallus endosubstratic, not visible, very rarely thinly episubstratic and bluish green. Apothecia lecanorine, sessile, 0.3-0.6(-0.9) mm across, with a pale to dark brown, slightly to heavily pruinose disc and a white-pruinose, prominent, usually weakly incised thalline margin. Thalline exciple 75-90 μm thick, with an indistinctly delimited cortex obscured by granules which are insoluble in K but soluble in N; proper exciple almost indistinct; epithecium yellowish brown, with superficial coarse granules insoluble in K and soluble in N and a fine epipsamma of crystals located above the paraphyses tips, which are insoluble in K and soluble in N; hymenium colourless, 35-60 µm high; paraphyses simple, thick, slightly expanded or capitate, brown pigmented at tips, usually free in K; hypothecium colourless. Asci 8-spored, clavate, very thin-walled, with a K/I+ blue, tall tholus penetrated by a faintly amyloid apical cushion, the wall K/I-, surrounded by a blue outer layer, Lecanora-type. Ascospores 1-celled, hyaline, ellipsoid, (8-)9-13(-16) x 4-5(-7) µm. Photobiont chlorococcoid. Spot tests: thallus (apothecial margin) K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
