Distribution: N - Lig (Navarro-Rosinés & al. 2000). C - Marc (Herb. Vondrák 8850).
Description: Thallus crustose, endosubstratic to usually episubstratic, irregularly areolate, yellow to rarely yellow-orange, forming 5-15 mm wide, irregular patches. Areoles 0.3-0.9 mm wide, flat to almost bullate, scattered to contiguous. Apothecia zeorine, 0.3-0.8(-1.5) mm across, sessile, constricted at base, round or irregular in outline, with a flat to convex, yellow-orange disc, a concolorous, thick, thalline margin, and a more or less evident parathecial ring. Thalline exciple rich in algal cells, usually limited to the basal parts of the apothecium; proper exciple of radiating hyphae; epithecium orange, 8-15 μm high, granulose, K+ red; hymenium colourless, 45-90 µm high; paraphyses simple or sparingly branched, 1.5-3 µm thick at base, the apical cells to 3-6(-7) µm wide; hypothecium colourless, inspersed with oil droplets. Asci (6-)8-spored, clavate, Teloschistes-type. Ascospores 1-septate, polarilocular, hyaline, broadly ellipsoid, (7-)9-14(-17) x (4.5-)6-7.5(-9) μm, the septum 3-6.5 µm thick, the lumina sometimes sandglass-shaped. Photobiont chlorococcoid. Spot tests: thallus and apothecia K+ red, C-, KC-, P-. Chemistry: thallus and apothecia with parietin (major), fallacinal, emodin, teloschistin and parietinic acid (minor), corresponding with chemosyndrome A of Søchting (1997).
Note: a recently-described species, resembling Caloplaca inconnexa, but non-parasitic and with different spores and ecology, found on horizontal or weakly inclined surfaces of compact calciferous rocks, especially in fissures; perhaps more widespread in Mediterranean Italy. The sample from Marche was collected at Ancona, on coastal rocks.
