Description: Thallus crustose, thin, usually continuous, rarely cracked, grey to usually dark lead grey, often delimited by a blue-grey prothallus, forming small patches, but often several thalli merging to cover larger surfaces. Apothecia common, zeorine, constricted at base, 0.4-0.7(-1) mm across, with an initially concave, then usually flat, brown-red to dark red disc, a thick, persistent, smooth thalline margin, and an orange to blackish parathecial ring. Thalline exciple corticate in lower part, paraplectenchymatous; proper exciple usually well-developed, up to 30 μm wide, colourless in inner part, sometimes with a dark grey, K+ violet outer rim; epithecium brownish orange, K+ red; hymenium colourless, 55-80 μm high, amyloid; paraphyses simple or forked, septate, c. 1 μm thick at base, the uppermost cells up to 4 μm wide; hypothecium colourless. Asci 8-spored, clavate, functionally unitunicate, apically thickened with a broad internal beak, the inner part of apex and external cap I+ blue, Teloschistes-type. Ascospores 2-celled, polarilocular, hyaline, ellipsoid, 11-14(-16) x (5-)7-8(-9) μm, the equatorial thickening (“septum”) 4-8 μm, 1/4-1/2 of spore length. Pycnidia immersed, subglobose, dark grey. Conidia bacilliform to short-cylindrical, hyaline, 4-5 x c. 1 μm. Photobiont chlorococcoid. Spot tests: thallus K- (but cortex and apothecial margin K+ faintly violet in section), C-, KC-, P-; apothecial disc K+ red. Chemistry: anthraquinones in the epithecium, Sedifolia-grey pigment in cortex.
Note: a mild-temperate to Mediterranean lichen found on smooth bark, especially common, especially on Ficus carica, throughout Mediterranean Italy. The species, despite its strong similarity with Caloplaca cerina, is not closely related to it.
