Description: Thallus not evident, not lichenized. Apothecia long-stalked, 0.6-1 mm high, pin-like, developing on the thalli of Chaenotheca trichialis. Stalk black, epruinose, 0.08-0.1 mm thick, the central part formed by pale, periclinally arranged hyphae, the outer part dark reddish brown. Capitulum lenticular 0.3-0,4 mm across, the outer part faintly bluish white-pruinose. Excipulum 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 isodiametric cells with sclerotized walls. Epithecium brown, poorly evident; mazaedium not present; 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. Photobiont absent. Spot tests: ascocarps K-, C-, KC-, P-. Chemistry: without lichen substances.
Note: parasitic or parasymbiotic in the thalli of Chaenotheca trichialis, mainly on old conifers, much more rarely on lignum and deciduous trees, mostly in upland areas; probably occurring in the Alps, but very much overlooked. The record from Sicily by Grillo (1996), not validated by Puntillo & Puntillo (2009) is not accepted here.
