Apothecia crowded, often mutually deformed, sessile, erumpent from bark, disc flat, dark purplish brown drying black, 1-3 mm. across , orbicular to elliptical or irregular, with a prominent obtuse margin when dry; receptacle smooth and black. Excipulum composed of parallel short-celled hyphae, 4-5 µ wide, with thin purplish brown walls, lying almost at right angles to the surface, the terminal cells black and opaque. Asci narrowly cylindric clavate, 140 x 5-6 µ, apex flattened, not greatly thickened, not blued by Melzer's reagent; ascospores uniseriate, 1-septate and constricted at the septum, dark brown, 12-13 x 3.5-4.5 µ; paraphyses cylindrical, obtuse, 3 µ wide, hyaline, firmly coherent.

The narrowly cylindrical asci with negative iodine reaction are not those of a Karschia.
