Description: Thallus crustose, endosubstratic, continuous to finely rimose, pinkish orange, yellowish, brownish or grey, without a distinct prothallus. Apothecia immersed in the thallus and often separated by a circular crack, 0.2-0.7 mm across, rounded or irregular in outline, with an initially concave, then flat, pink to pale brown disc, and a rather evident, whitish margin. Proper exciple thin, poorly developed; epithecium colourless, K-, N-; hymenium colourless, (75-)100-120(-140) µm high; paraphyses simple or sparingly branched, submoniliform in upper part, the apical cells slightly swollen; hypothecium colourless. Asci 8-spored, cylindrical-clavate, the outer coat I+ blue, but the inner walls and apical dome K/I-. Ascospores 1-celled, hyaline, ellipsoid, 13-22 x 5-12 µm. Pycnidia immersed, pale, the wall colourless, N-. Conidia bacilliform. Photobiont trentepohlioid, the cells 10-18 µm wide. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
Note: an arctic-alpine to cool-temperate, circumpolar species found on hard, compact calciferous rocks, such as limestone, dolomite, calcareous schists, in sheltered-humid situations; most frequent in the Alps, but reaching south to Calabria along the Apennines.
