Description: Thallus crustose, episubstratic, continuous or rimose, chalky white, often with a bluish tinge, 0.2-1.2 mm thick, most often without a clear prothallus, rarely delimited by a thin dark prothalline line. Medulla white, I+ deep blue. Apothecia lecideine, black, epruinose, (0.2-)0.4-2(-3) mm across, with a flat to finally strongly convex disc and a persistent, raised, wavy proper margin. Proper exciple green-black to brown-black along a thin outer rim, colourless or pale grey within, C+ orange-red; epithecium green-black, K-; hymenium bright blue green, rarely brownish or colourless, 50-70 µm high; paraphyses coherent, simple or forked in upper part, c. 2 µm thick at mid-level, the apical cells hardly swollen, to 2.6 µm wide; hypothecium dark brown, K-. Asci 8-spored, clavate, Lecidea-type. Ascospores 1-celled but often pseudodiblastic, hyaline, ellipsoid, 6-12 x 3.5-6.5 µm, not halonate, thin-walled. Pycnidia black, globose, immersed. Conidia bacilliform, 5-15 x 0.8-1.5 µm. Photobiont chlorococcoid. Spot tests: thallus K- or K+ faintly yellow, C-, KC-, P-. Chemistry: thallus and exciple with 2'-O-methylanziaic acid.
