Description: Thallus not evident, not lichenized. Apothecia short-stalked, 0.15-0.36 mm high, or rarely subsessile. Stalk black or dark brown, of periclinally arranged hyphae, pale in inner part, dark brown to reddish in outermost part (section). Capitulum subglobose to obovoid, 0.14-0.26 mm across. Exciple well-developed, of brown, more or less periclinally arranged hyphae; mazaedium well-developed, black. Asci 8-spored, cylindrical, formed singly from ascogenous hyphae with croziers, with a single, functional wall layer, K/I-, disintegrating at a rather late stage, with uniseriately arranged spores. Ascospores 1-celled, subfusiform, with pointed ends, dark brown, 10-15.5 x 6.5-9 µm, with an ornamentation of longitudinal coarse ridges. Photobiont absent. Spot tests: K-, C-, KC-, P-. Chemistry: without lichen substances.
