Description: Thallus crustose, episubstratic, rarely endosubstratic and poorly evident, usually composed of convex, white to pale grey-green, smooth, ecorticate areoles, sometimes reacting K+ violet. Apothecia micareoid, sessile, 0.1-0.5 mm across, sometimes aggregated into up to 0.8 mm wide clusters, with a dark grey to black (pale grey to whitish in shade-forms), strongly convex, sometimes tuberculate, epruinose disc, without a proper margin or with a thin whitish margin evident only in young apothecia. Proper exciple indistinct or very thin, of paraphysis-like hyphae; epithecium hardly separate from the hymenium; hymenium olive-grey, brownish, olive-brown or dull grey in upper part, colourless in lower part, 25-40 µm high, the pigmented parts C+ pink; paraphyses numerous, branched and anastomosing, 1-1.7 µm thick, not capitate; hypothecium colourless, 60-110 µm high. Asci 8-spored, clavate to cylindrical-clavate, clavate, in K/I with a blue outer layer and apical dome and unstained wall, the dome with an apical cushion. Ascospores (0-)1(-2)-septate, often with slightly unequal cells, hyaline, narrowly ellipsoid, oblong-ellipsoid or fusiform with rounded ends, straight or slightly curved, (6-)8-14(-18) x 2-3.5(-4) µm. Pycnidia immersed to emergent-stalked, grey to black, the wall greenish, K+ violet, C+ red-violet. Conidia of three types: i) macroconidia, curved, (1-)3 septate, 12-24 x 1 µm; ii) mesoconidia, simple, 2.5-4.5 x 1-2 µm, extruded as a white mass from the ostiole; iii) microconidia, simple, 5-7.5 x 0.5-1 µm. Photobiont micareoid, thin-walled, the cells 4-7(-8) μm wide. Spot tests: thallus, apothecial and pycnidial sections K- or K+ faintly violet, C+ red, KC+ red, P- (reactions best visible under the microscope). Chemistry: gyrophoric acid.
