Distribution:

Description: Thallus crustose, whitish to greenish-grey, 30-50 µm thick, paraplectenchymatous, not subgelatinous when wet, without a distinct prothallus. Perithecia black, 50-160 µm across, immersed to semi-immersed, the upper part exposed or covered by a thin thalline layer. Involucrellum present, 130-235 x 45-90 µm, 12-70 µm thick; exciple of cellular hyphae, brown-black in upper part, pale or colourless in lower part; pseudoparaphyses slender, branched and anastomosing, long-celled, c. 1 μm thick; periphyses absent; hymenial gel I-. Asci 8-spored, cylindrical, K/I-, fissitunicate, the apical dome with an indistinct ocular chamber, with biseriately arranged ascospores. Ascospores 1-septate, with equal or slightly unequal cells, hyaline, 9-15 x 3.6-7 µm. Pycnidia unknown. Photobiont trentepohlioid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.

Note: an apparently rare, amphibious freshwater species growing submerged or slightly above water level on siliceous rocks and pebbles, restricted to shaded sites in upland areas. Known only from a few localities in Germany (Hesse), Austria (Styria, Carinthia), and France (Puy-de-Dôme), the species should be looked for in Italy.
