Distribution: N - Frl, Ven (Nascimbene & al. 2006), TAA (Nascimbene & al. 2004, 2004b, 2022, Nascimbene 2008b), Lomb, Piem (Isocrono & al. 2004), VA (Nascimbene & al. 2021).
Description: Thallus crustose, episubstratic, 0.1-0.5 mm thick, areolate-subsquamulose, mostly white, sometimes with a grey or brownish hue. Areoles smooth, up to 1 mm wide, contiguous or slightly imbricate, moderately to strongly convex, the margins somehow darker and down-turned, forming a compact crust. Apothecia frequent, without a thalline margin, sessile and slightly constricted at base, 0.4-1.5 mm across, with an orange to orange-brown (blackish brown in old apothecia), mostly convex, smooth disc, and a very thin, soon excluded proper margin. Proper exciple poorly developed, of parallel-radiating, branched hyphae, colourless to patchily orange-brown; epithecium orange-brown, 10-18 μm high, with granular crystals reacting K+ red; hymenium colourless, 60-110 μm high, hemiamyloid; paraphyses coherent, sparingly branched and anastomosing, 2-3.5 μm thick, the apical cells hardly swollen, up to 4 μm wide; hypothecium at first colourless, then brownish, patchily pigmented. Asci 8-spored, elongate-clavate, with a thin, outer amyloid layer and a thickened tholus penetrated by a tube, the sides of which stain I/KI+ deep blue, Porpidia-type. Ascospores 1-celled, hyaline, ellipsoid to ovoid, thin-walled, 9-12(-13.5 )x 4-6(-7) μm, without a distinct perispore. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-; apothecia K+ red. Chemistry: apothecia with anthraquinones, mainly parietin. Note: on soil over weakly calcareous or dolomitic substrata in upland areas, more rarely on weathered calciferous rocks.
