Description: Thallus crustose, thin, partly endosubstratic, greenish grey to ash-grey, usually continuous. Perithecia black, 0.3-0.45 μm across, globose, one-quarter to half-immersed, partly covered by a thin thalline layer when young. Involucrellum dark brown, dimidiate, distinct from the exciple when young, later usually appearing as a thickening of the upper part of exciple, the latter colourless to pale brown in upper part; hamathecium of thread-like paraphysoids which are mostly simple, and only rarely branched and anastomosing, except where adjacent to the exciple. Asci 8-spored, narrowly clavate, bitunicate-fissitunicate, shortly stalked at base, the apex thickened into a tholus, with a narrow ocular chamber, I-. Ascospores (5-)7(-9)-septate, hyaline, fusiform, 25-35(-40) x (3.5-)5.5-7(-8) μm, rarely also with a longitudinal septum, without a perispore. Pycnidia, often of two types. Macropycnidia black, c. 0.1 μm across; macroconidia subapically inserted on the conidiogenous cell, 5-7-septate, not or scarcely constricted at the septa, cylindrical, 20-30 x 4-6 μm, with apical gelatinous appendages. Micropycnidia c. 0.05.0.1 mm across; microconidia 2.5-3 x 0.5-1.5 μm. Photobiont trentepohlioid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: thallus without lichen substances.
