Description: Thallus crustose, not lichenized, continuous, effuse, immersed in the bark, pale grey to yellowish grey, somewhat glossy, smooth. Perithecia flattened-hemispherical, black but partially covered by a grey layer of bark cells, semi-immersed in the thallus, c. 0.2-0.5(-0.6) mm across. Involucrellum dark brown, mingled with bark cells; exciple 200-400 μm wide, black, absent below the hamathecium; hamathecium of branched pseudoparaphyses, anastomosing above the asci, c. 1 μm wide, not inspersed with oil droplets, degenerating fairly soon. Asci 8-spored, clavate, thick-walled, the inner wall thickened towards apices, with a shallow, broad ocular chamber Ascospores submuriform, with 5-7 transversal septa and 1-2 longitudinal septa, hyaline, narrowly ellipsoid to narrowly ovoid, 14-20(-25) x 6-9(-10) μm, with a c. 2-3 μm thick gelatinous perispore. Pycnidia black. Conidia bacilliform, 8-10 x 1-1.5 μm. Photobiont absent. Spot tests: thallus K-, C-, KC-, UV-. Chemistry: without lichen substances.
Note: a non-lichenized fungus growing on smooth bark, perhaps identical to Arthopyrenia fallaciosa (Orange 2013).
