Description: Thallus crustose, endosubstratic or thinly episubstratic, continuous or rarely rimose, white to rusty red, often poorly evident and reduced to a collar around the apothecia. Apothecia 0.2-0.6 mm across, sessile, urceolate and almost perithecioid when young, with a concave, pale orange to dark brown disc, and a rather thick, brown to brown-black, sometimes fissured proper margin. Proper exciple 30-40 µm wide at base, c.100 µm wide laterally, dark brown in outer part, colourless within; epithecium pale brown; hymenium colourless or pale brown in upper part, (80-)100-120(-160) μm high; paraphyses mostly simple, 0.8-1.5 µm thick, embedded in a gelatinous matrix; hypothecium very pale brown. Asci 6-8-spored, clavate, thin-walled except for a slightly thickened apical tholus, K/I-, 76-120 x 25-45 µm. Ascospores muriform, with 5-7 transverse septa and 2-3 longitudinal septa, hyaline, broadly ellipsoid to subglobose, (18-)24-35(-43) x (10-)12-16(-21) μm, sometimes attenuated at one end. Photobiont chlorococcoid, the cells 7-17 μm wide. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
