Description: Thallus inapparent, the hyphae immersed into gelatinous algal films, probably not lichenized (perhaps a parasite of algal colonies). Perithecia half-immersed, globose, 0.1-0.15 mm across, dark brown to almost black in upper part, sometimes paler in lower part, with a 10-15 μm thick, colourless gelatinous coat. Exciple 10-15 µm thick laterally, c. 30 µm thick near the ostiole, of pigmented, periclinally oriented hyphae; paraphyses thread-like, c. 1 μm thick, mostly simple. Asci 8-spored, cylindrical-clavate, moderately thick-walled, non-fissitunicate, the entire ascus wall I+ and K/I+ blue, (40-)45-55(-60) × 8-11.5 µm. Ascospores 1(-2)-septate, not or only slightly constricted at septum, hyaline, narrowly ellipsoid, straight or slightly curved, (10-)12-15(-17) x 3.5-4.5(-5) µm, with (2-)4-8(-10) µm long, thread-like appendages at both ends. Pycnidia 40-90 µm across. Conidia simple, rod-like, 2-3 x c. 0.5 µm. Photobiont absent but the species is associated with Coccomyxa-like or other chlorococcoid algae. Spot tests: all negative. Chemistry: without lichen substances.Note: on algal colonies developing on acid soil and pioneer mosses. To be looked for in Italy.
