Description: Thallus crustose, grey to whitish-pruinose, sometimes poorly evident, very thin and film-like, more or less continuous. Apothecia frequent, lecanorine, rounded, sessile, strongly constricted to almost substipitate, 0.5-1(-1.5) mm across, the disc greenish-yellow, sometimes becoming darker olive-yellow with age, mostly concave to flat, yellow-pruinose or rarely epruinose; thalline margin thick, raised, smooth, grey to white-pruinose, mostly entire, sometimes flexuose. Epithecium yellowish, K+ purple-red; hymenium colourless, 70-85 μm high; paraphyses branched in upper part, the apical cells 3-4 μm thick; 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, (10-)12-15(-19) x (4-)6-8.5(-11) μm, the equatorial thickening (“septum”) 5-7(-9) μm. Photobiont chlorococcoid. Spot tests: thallus K- or K+ faintly violet (reaction best visible on thick sections under the microscope), C- or C+ violet, KC-, P-; disc of apothecia K+ purple-red. Chemistry: thallus with the Sedifolia-grey pigment; disc of apothecia with parietin (major), fallacinal, emodin, teloschistin and parietinic acid (minor).Note: a mainly arctic-alpine, circumpolar lichen found on mosses and plant debris in tundra-like habitats, especially in areas with calcareous or basic siliceous rocks, to be looked for in the mountains of Sicilia. This is the only taxon hosting the parasite Stigmidium cerinae, which suggests that it is an independent species. The Caloplaca cerina-like lichens growing on the ground on various substrata such as bryophytes, plant debris, bark of exposed roots and chamaephytes have been molecularly analysed by Šoun & al. (2011), who found that they form four monophyletic groups and six ecotypes, which cannot be always distinguished on the basis of morphological characters. Here we place alpine-subalpine populations growing on calcareous substrata, with pale apothecial discs. See also note on C. cerina.
