Symb. Bot. Upsal., 21, 2: 116, 1975.

Description: Thallus not evident, not lichenized. Apothecia long-stalked, 0.6-1 mm high, pin-like, developing on the thalli of Chaenotheca trichialis. Stalk 0.05-0.07 mm thick, black, epruinose, 0.08-0.1 mm thick, consisting of an outer, 6-9 µm thick layer of strongly sclerotized, dark brown hyphae, and an inner part of iregularly interwoven, colourless and swollen hyphae. Capitulum lenticular 0.3-0.4 mm across, the outer part faintly bluish white-pruinose; mazaedium not present. Exciple dark brown, 20-50 µm thick (thickest at the base), 3-layered, the innermost and median layer of periclinally arranged hyphae, the outer layer of more or less isodiametrical cells with sclerotized walls. Epithecium brown, poorly evident; hypothecium aeruginose green, 60-80 µm high. Asci 8-spored, cylindrical, with a thickened apex penetrated by a narrow canal, formed singly, persisting until the spores are mature. Ascospores 1-septate, brown, ellipsoid, 6-8 x 2-2.5 µm, with a smooth wall, the septum clearly pigmented, at least as dark as the wall. Photobiont absent. Spot tests: all parts of ascocarps K-, C-, KC-, P-, N-. Chemistry: without lichen substances.
