Description: Thallus inapparent, the hyphae immersed into gelatinous algal films, probably not lichenized (perhaps a parasite of algal colonies). Ascocarps perithecioid, globose, sometimes flattened at apex, 0.1-0.2(-0.25) mm across, pale to dark grey or brown-black, surrounded by a thin, colourless gelatinous layer, with a ring-like swelling around the ostiole. Exciple 2-layered, of periclinally oriented hyphae, pale brown to dark greenish brown at least in upper part, 25-35 µm thick (thicker in upper half); paraphyses thin, thread-like, somehow thicker in middle part, simple. Asci 8-spored, cylindrical-clavate, moderately thick-walled, non-fissitunicate, the entire ascus wall I+ and K/I+ blue, (30-)40-70(-87) x (10-)11-15(-16) µm. Ascospores 3-septate, not constricted at septa, hyaline, narrowly ellipsoid to fusiform, thin-walled, (18-)24-35(-40) x 3-4.5(-5.5) µm, with 2-4(-8) µm long, thread-like appendages at both ends. Photobiont absent but the species is associated with Coccomyxa-like or other chlorococcoid algae. Spot tests: all negative. Chemistry: without lichen substances.
