Distribution:

Description: Thallus inapparent, the hyphae immersed into gelatinous algal films, probably not lichenized (perhaps a parasite of algal colonies). Perithecia globose, depressed in apical part around the ostiole, (0.06-)0.08-0.18 mm across, greyish, dark green, slightly brownish to shiny black, surrounded by a thin, colourless gelatinous coat. Exciple 2-layered, brownish at least in upper part, of periclinally oriented hyphae, not easily breakable in squash preparations; paraphyses thread-like, 1.5-2 μm thick, simple or rarely forked in upper part. Asci 8-spored, cylindrical-clavate, moderately thick-walled, non-fissitunicate, the entire ascus wall I+ and K/I+ blue, (40-)45-60(-80) x (8-)9-12 μm. Ascospores 1-septate, ellipsoid to narrowly ellipsoid, often with unequal cells (soleiform), hyaline, thin-walled, (10-)11-15(-18) x 4-5.5(-6.5) μm, without appendages at the ends. Photobiont absent but the species is associated with Coccomyxa-like or other chlorococcoid algae. Spot tests: all negative. Chemistry: without lichen substances.

Note: parasitic on algal colonies developing on acid soil and moribund silicicolous mosses; reported from the Eastern Alps (Austria); to be looked for in Italy.

Substrata: soil, terricolous mosses, and plant debris
