Distribution: N - TAA (Navarro-Rosinés & al. 2007).

Description: Thallus crustose, greyish brown to whitish grey, 0.15-0.4 mm thick, consisting of scattered or contiguous areoles developing on Leproplaca proteus. Areoles rounded, angular or irregular, (0.2-)0.3-0.6(-0.9) mm wide, smooth or rugose, slightly concave to convex, matt, slightly attenuated at the base, the margins concolorous with upper surface or slightly darker, but never black. Cortex paraplectenchymatous, of a single layer of cells with brown pigment, partially overlain by an epinecral layer; medulla 100-200 μm thick, with some crystals in lower part, I-. Perithecia 1-5(-10) per areole, entirely immersed or projecting only with the black ostiolar region. Involucrellum absent; exciple globose, 150-180 μm across, the wall paraplectenchymatous, 15-18 μm thick, colourless except around the ostiole. hamathecium of periphyses along the ostiolar channel, pseudoparaphyses in upper part of the perithecium, and paraphyses disappearing early; periphyses 15-16(-20) μm long. Asci 8-spored, clavate, bitunicate, with a thin tholus reacting I-, Verrucaria-type. Ascospores 1-celled, hyaline, ellipsoid, 15-20 x 6-8.5 μm. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.

Note: a lichenicolous lichen growing on the thalli of Leproplaca proteus; to be looked for in the Italian Alps (the record is from Austria, but not far from the border).
