Description: Thallus crustose, areolate-subsquamulose or verrucose-areolate, forming 3-20(-30) mm wide patches on the thalli of Calogaya biatorina. Areoles crowded, rounded or irregularly polygonal, (0.3-)0.6-1.6(-2) mm wide, 0.4-0.8 mm thick, flat to convex, attached by the central part and sometimes substipitate, grey brown with black margins and lower surface, usually epruinose. Cortex 8-15 µm thick, of 1-3 layers of pale brown cells, rarely covered with a thin, discontinuous epinecral layer; medulla white, dense, filled by crystals and substrate particles, I-. Perithecia black, 0.15-0.3 mm across, globose, immersed in the areoles. Involucrellum absent; exciple 15-20 µm thick, paraplectenchymatous, colourless except around the ostiole; hymenium colourless, I+ reddish; hamathecium of periphyses along the ostiolar channel and periphysoids in upper part of the perithecium, the paraphyses disappearing early; periphysoids 18-27 x 2,5-4 μm. Asci 8-spored, clavate, bitunicate, with a thin tholus reacting I-, Verrucaria-type. Ascospores 1-celled, hyaline, ellipsoid, (8.5-)11-13.5(-16) x 6-9.5 μm, (1.3-)1.4-2(-2.5) times as long as wide. Pycnidia black, globose, immersed, Dermatocarpon-type, the wall colourless except at the brown apex. Conidia simple, bacilliform, 4.5-6 x 1-1.5 μm. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
