Description: Thallus not evident, not lichenized. Apothecia stalked, pin-like. 0.3-0.5 mm high, the stalk 0.04-0.1 mm thick, black or rarely brown in lower part, the central part hyaline, formed by periclinally arranged hyphae, the outer part formed by irregularly intertwined, medium brown hyphae. Capitulum lenticular to hemispherical, 0.15-0.22 mm across, black; mazaedium absent. Exciple well-developed, of dark brown, periclinally arranged hyphae; epithecium thin, brownish; hypothecium 55-65 µm high, colourless to yellowish brown. Asci 8-spored, cylindrical, with a thickened apex penetrated by a narrow canal, formed singly, persisting until the spores are mature. Ascospores 1-septate, pale brown, ellipsoid, 5.5-7 x 2-2.5 µm, with a poorly pigmented, thin septum and a smooth wall. Photobiont absent. Spot tests: all brown or reddish pigmented parts K+ red, the reaction rapidly fading and the tissue turning greenish brown. Chemistry: an undidentified reddish pigment.
