Description: Thallus crustose, episubstratic, coarsely areolate-verruculose to subsquamulose, whitish o brownish white, esorediate, the a reoles 0.25-1 mm wide, convex, sometimes with raised margins and appearing subsquamulose. Apothecia biatorine, 0.3-1.2 mm across, adnate, not or only slightly constricted at base, reddish brown to cinnamon-brown (old apothecia sometimes almost black), with a convex, often tuberculate disc, and a very thin, paler, soon excluded proper margin. Proper exciple 50-120 µm wide laterally, of radiating hyphae, dark brown to reddish brown in outer part, colourless or yellowish within; epithecium scarcely differentiated from the hymenium, colourless to pale yellow; hymenium colourless or sometimes brown-striped, 50-80 µm high; paraphyses mostly simple, coherent, 1-2.5 µm thick at mid-level, the apical cells to 3 µm wide; subhymenium distinct, 50-100(-170) µm high; hypothecium 120-360 µm high, colourless or partly pale reddish brown to pale yellow. Asci 8-spored, cylindrical-clavate, with a K/I+ blue apical dome penetrated by a narrow, K/I- apical cushion surrounded by a narrow, deeply K/I+ blue zone, the wall K/I- but surrounded by a I+ red-brown and K/I+ blue outer layer, the ocular chamber small, Biatora-type. Ascospores 1-celled (rarely 1-2-septate), hyaline, narrowly ellipsoid, (10-)13-17(-22) x (3.5-)4.5-5.2(-6) µm, with a thin perispore. Pycnidia very rare, pyriform, colourless. Conidia fusiform or bacilliform, 4-6.5 x c. 0.8 µm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P+ orange-red. Chemistry: argopsin, norargopsin.
