Description: Thallus crustose, composed of whitish grey, ash- to more or less intensive greenish-grey, usually convex-granulose, 0.1-0.3 mm wide areoles, sometimes poorly developed. Areoles with a thick, hyaline, up to 25(-30) μm high amorphous layer. Apothecia micareoid, black or blue-black, sessile to substipitate, often tuberculate, 0.15-0.6(-0.9) mm across, with a convex to almost globose disc, without a proper margin. Proper exciple poorly developed and soon excluded, brownish in outer part, composed of branched, paraphysis-like hyphae; epithecium scarcely differentiated from the hymenium, usually intensive aeruginose or olive-green owing to the pigment present in the gel matrix and walls of paraphyses, K+ intensifying green; hymenium 50-75 μm high, colourless, or olivaceous to blue-green in upper and sometimes lower parts, the pigmented parts K-, N+ red, rarely with a few scattered, minute violaceous granules reacting K+ green; paraphyses numerous, 1.5-2 μm thick at mid-level, simple or sparingly branched in upper part, the apical cells 2.5-3 μm wide; hypothecium pale blue-green or olivaceous, K-, the central part often colourless or pale brown. Asci 8-spored, clavate to cylindrical-clavate, in K/I with a blue outer layer and apical dome and unstained wall, the dome with an apical cushion, 40-50 x 10-16 (-18) μm. Ascospores (3-)4-7-septate, hyaline, fusiform to narrowly fusiform, straight or slightly curved, rounded at one end and acute at the other, (14-)16-36(-38) x (3.5-)4-6(-7) μm. Pycnidia more or less immersed, the wall green (K-) in upper parts, producing three types of conidia: a) curved, 3-7-septate macroconidia measuring 16-22 x c. 1 μm, b) cylindrical to obovoid mesoconidia measuring 4-7 x 1.5-2 μm, c) narrowly cylindrical microconidia measuring 5-7 x c. 0.8 μm. Photobiont micareoid, the cells 4-7 μm wide. Spot tests: thallus K-, C-, KC-, P+ orange-red; apothecial sections C-. Chemistry: thallus with argopsin.
