Description: Thallus crustose, areolate or subsquamulose-areolate, forming 3-12 mm wide patches on the thalli of Calogaya pusilla. Areoles (0.2-)0.4-1(1.3) mm wide, (0,2-)0.3-0.65 μm thick, polygonal to rounded, flat to convex, brown to almost black, not or only weakly pruinose. Cortex 7-13 μm thick, of 1-2 layers of pale brown cells, generally covered with an epinecral layer; medulla white, with many large crystals, I-. Perithecia black, 0.13-0.19 mm across, 2-8(-16) per areole, globose, immersed. Involucrellum absent; exciple paraplectenchymatous, colourless except around the ostiole; hymenium colourless, I+ reddish; hamathecium of periphyses along the ostiolar channel, pseudoparaphyses in upper part of the perithecium, and paraphyses disappearing early. Asci 8-spored, clavate, bitunicate, with a thin tholus reacting I-, Verrucaria-type. Ascospores 1-celled, hyaline, ellipsoid, 9-13 x 4.5-6 μm. Pycnidia infrequent, black, 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.
