Distribution: N - VG, Ven (Lazzarin 2000b), Lomb (Gheza & al. 2023), Emil (Fariselli & al. 2020). C - Tosc, Abr. S - Pugl (Jatta 1909-1911).
Description: Thallus crustose, endosubstratic or thinly episubstratic and slightly rimose in the surroundings of the perithecia, pale grey to cream-coloured, delimited by a brown-black line. Perithecia black, 70-100/cm2, 0.26-0.54 mm across, 1/2 to 3/4 immersed in the rock, leaving deep pits when they fall off, the ostiole paler, flat to depressed. Involucrellum apical, c. 50-80 µm thick, appressed to exciple; exciple globose, c. 0.24-0.42 mm across, the wall medium to dark brown; hamathecium of branched periphysoids measuring 40-50 x c. 2 µm, interascal filaments absent; hymenial gel hemiamyloid, I+ red (I+ blue at very low concentrations of I), K/I+ blue. Asci 8-spored, subcylindrical to oblong-clavate, I-, fissitunicate, the wall thickened above, Verrucaria-type. Ascospores 1-celled, hyaline, ellipsoid, (26-)27-38 x (11-)13-17(-18) µm. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances. -
Note: on calcareous rocks and pebbles, usually near the ground. A species belonging to the poorly understood complex of V. hochstetteri, also reported from several localities in the Austrian and French Alps, differing from V. foveolata in the small apical involucrellum (see Pykälä & al. 2020).
