TYPE. RUSSIA. Primorsky [Krai], Lazo region, Lazovsky reserve, ~5 km south of “kordon  Korpadj”. Alt. ~200 m. On the bark of Phellodendron amurense in very shaded and moist situation in mixed Pinus-deciduous forest, 1990, Titov 3826 (LE, holotype; UPS, isotype).

Description. Life form: borderline lichen.

[Modified from Titov 1993] Thallus absent; ascomata associated with Trentepohlia alga. Ascomata stalked apothecia, small, (0.20-)0.23-0.33(-0.40) mm high, black, without pruina. Capitulum obconical, later lenticular to subspherical, often irregular (0.08-)0.10-0.20(-0.30) mm in diameter. Epithecium thin, pale; hypothecium 60-80 μm high; hymenium and hypothecium greenish brown. Excipulum brown, 8-15 μm thick, formed by 2-3 layers of isodiametric to slightly elongated and periclinally arranged, thick-walled, ~34 μm large cells. Stalks straight, (0.02-)0.03-0.05(-0.07) mm in diam., shiny black. Outer part of stalk consists of thick-walled, brown, periclinally arranged cells. Central part of stalk formed by pale, interwoven and largely periclinally arranged hyphae. All parts of the apothecium H-, K-. Asci (28.0-)29.4-35.3(-40.5) x (2.8-)2.9-3.4(-3.7) μm, cylindrical or narrowly clavate. Ascus apex thickened and penetrated by a fine canal. Ascospores uniseriately or sometimes biseriately arranged in the asci, periclinally or slightly obliquely orientated. Ascopores non-septate, ellipsoidal to allantoid, brown, (4.5-)5.1-6.7(=8.0) x (1.8-)2.0-2.9(-3.0) μm. Surface of mature  spores  smooth or with a  very minute ornamentation  under the light microscope, slightly ornamented in SEM (scanning electron microscopy).

Substrate and Habitat. Corticolous on trees in moist forests.

Distribution. Temperate-boreal East Asia-eastern North America disjunct; in North Carolina found in the Blue Ridge ecoregion.
