in Roux, Bull. Soc. linn. Provence, num. spéc. 16: 216, 2012. Basionym: Lecanora cheresina Müll. Arg. - Rev. Mycol., 2: 75, 1880.
Synonyms: Aspicilia cheresina (Müll. Arg.) Hue; Aspicilia cheresina var. granuligera (J. Steiner) Szatala?
Description: Thallus crustose, episubstratic, white to pale grey, continuous to rimose in peripheral parts, areolate in central parts, very well delimited (sometimes by a black prothallus), forming orbicular patches on the thalli of Circinaria calcarea; the marginal part of the thallus is often radially cracked, giving it an almost placodioid appearance, the central areoles are angular, flat and smooth. Apothecia lecanorine-aspicilioid, 0.2-1 mm across, irregular in outline, from round to elongate or angular, immersed in the areoles, with a black, often grey-pruinose, concave to flat, smooth disc and a very slightly raised thalline margin. Epithecium greenish brown; hymenium colourless; paraphyses more or less branched and anastomosing; hypothecium colourless, subtended by a continuous algal layer. Asci (6-)8-spored, clavate, the thin outer coat K/I+ blue, the wall and apical dome K/I-. Ascospores 1-celled, hyaline, broadly ellipsoid, 8-14(-16) x 5-10 μm, 1-2-seriate in the asci. Pycnidia immersed, black, the wall colourless in sections except around the ostiole. Conidia bacilliform, 4-5 x c. 1 μm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
