Description: Thallus crustose, thinly episubstratic, bright green to olive-green, subgelatinous when wet, granular, consisting of densely crowded, globose, to 12-18 µm wide goniocysts, which sometimes coalesce forming up to 60 µm wide, isidia-like granules, the outer hyphae with a greenish, K+ violet pigment. Apothecia micareoid, round, sessile, not constricted at base, 0.2-0.4 mm across, creamy white, pale grey to partly dark grey, sometimes brownish, strongly convex, hemispherical to subglobose, sometimes tuberculate and up to 0.8 mm across, without a distinct proper margin. Epithecium colourless to grey, sometimes with crystals visible under polarized light, when pigmented K+ violet, N-; hymenium colourless, 30-60 µm high; paraphyses numerous, richly branched and anastomosing, 0.5-1(-1.2) µm thick, the apical cells to 2 µm wide; hypothecium colourless or rarely very pale yellow. Asci 8-spored, clavate to cylindrical-clavate, with an unstained wall and a K/I+ blue outer layer and apical dome, the latter with a non-amyloid, cylindrical axial mass, 25-55 x 8-12 μm. Ascospores 0-1(-3) septate, hyaline, ovoid to oblong-ellipsoid, (7-)8-12(-14) x (2.5-)3-4(-5.5) µm. Pycnidia frequent, white or grey around the ostiole, K+ and C+ more or less violet, of 2 types: a) mesopycnidia 50-150 µm wide, globose or barrel-shaped, with a wide ostiole, producing cylindrical to obpyriform mesoconidia measuring 4-6 x 1-1.5 µm; b) micropycnidia 30-60 µm wide, globose, producing bacilliform or narrowly fusiform microconidia measuring 4-5.5- x 0.5-1 µm. Photobiont micareoid, the cells 4.5-7 μm wide. Spot tests: thallus and apothecia K-, C-, KC-, P-, UV- (except for the pigment in the outer hyphae of the goniocysts and in the apothecia, which reacts K+ violet). Chemistry: micareic acid, variable amounts of Sedifolia-grey pigment in apothecia.Note: a temperate to boreal-montane species found on basal parts of old, acid-barked trees, more rarely on rotting wood or on siliceous rocks, with a rather wide ecological amplitude. The species has been recently split into several cryptic species, whose occurrence and distribution in Italy were never studied in detail.
