Description: Thallus not evident, not lichenized. Apothecia stalked, black to dark brown, 0.4-1(-2) mm high, the stalk 0.04-0.1 µm thick, consisting of periclinally arranged, dark greenish brown to brown hyphae, the outer ones darker pigmented than the inner ones. Capitulum obconical to lenticular, 0.2-0.3 mm across, with a convex upper surface. Exciple brown, thin to rather thick, 15-50 µm wide, consisting of 3-4 layers of periclinally arranged hyphae; mazaedium absent; hypothecium broadly obconical, dark brown. Asci cylindrical, 39-42 x 3-3.5 µm, formed singly, with a single functional layer, strongly and uniformly thickened at apex, without a canal, with uniseriately arranged ascospores, persisting until the spores are mature. Ascospores 1-celled, dark brown, ellipsoid to fusiform, flattened, (5.5-)7-9(-11) x (2.5-)3.5-4(-5) µm, with a smooth or irregularly and minutely verrucose wall. Pycnidia black, with a distinct apical pore. Conidia more or less curved, pale brown, 4-5 x 1-1.5 µm. Photobiont absent. Spot tests: stalk K- or K+ slightly reddish brown, N- or N+ slightly intensified reddish brown. Chemistry: without lichen substances.
