Description: Thallus crustose, episubstratic, pale grey, epruinose, forming up to 2 cm wide patches, smooth or rimose, without a distinct prothallus. Cortex colourless, indistinctly paraplectenchymatous; medulla white, I-. Apothecia lecideine, black, 0.2-1.3(-1.5) mm across, immersed to subsessile, with a flat to convex, often pruinose disc, a thin sometimes excluded proper margin, and sometimes a pseudothalline margin in young apothecia. Proper exciple thin, brown in outer part, colourless to pale brown in inner part, of radiating hyphae; epithecium brown; hymenium colourless, 45-75 μm high, K/I+ blue; paraphyses simple, c. 2 μm thick at mid-level, the apical cells slightly capitate, up to 3 μm wide; hypothecium brown. Asci 8-spored, clavate to cylindrical-clavate, the apical dome K/I+ dark blue with a pale, conical-pointed apical cushion (axial mass), the wall I-, but the thin outer gel I+ blue, approaching the Bacidia-type. Ascospores at first 3-septate, then most often submuriform, brown, ellipsoid, sometimes slightly curved, thick-walled, (11-)13-20(-25) x (6-)8-10(-15) μm. Pycnidia rare, immersed, the wall brown in upper part, colourless in lower part. Conidia ellipsoid. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances. Note: a mild-temperate to southern boreal-montane lichen found on bark and on base-rich or slightly calciferous rocks, brick, roofing tiles etc., below the subalpine belt. See also note on D. nivale.
