Description: Thallus not evident, not lichenized. Apothecia long-stalked, pin-like 0.7-1.3 mm high. Stalk slender, black, the central part formed by colourless, intricately interwoven or partly periclinally arranged hyphae, the outer part formed by periclinally arranged, dark reddish brown hyphae. Capitulum obconical or subdivided into smaller capitula, 0.2-0.3 mm across, often faintly white pruinose on upper surface, with an excipulum of intertwined and sclerotized, reddish brown to dark brown, intertwined hyphae. Epithecium thin, reddish brown; mazaedium not present. Asci 8-spored, cylindrical, with a thickened apex penetrated by a narrow canal, formed singly, persisting until the spores are mature, with 1-seriate and periclinally arranged ascospores. Ascospores 1-septate, dark brown with a paler septum, ellipsoid, 6-8 x 2-2.5 µm, with a smooth wall. Photobiont absent. Spot tests: epithecium, excipulum and hypothecium K+ persisting green. Chemistry: an unidentified, reddish, K+ green pigment.
Note: parasitic or parasymbiotic on Chaenotheca chrysocephala on trunks of old trees in ancient and humid, montane to subalpine coniferous forests; certainly more widespread in the Alps, but not common.
