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, whitish-grey, not delimited by a black line. Perithecia black, 0.15-0.38 mm, fully or ¾-immersed in the rock, leaving deep pits in the rock when they fall off. Involucrellum apical, c. 50-90 µm thick, adpressed to exciple; exciple globose, c. 0.22-0.26 mm across, the wall pale to dark brown; hamathecium of branched periphyses and periphysoids measuring 30-50 x 1.5-2.5 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, c. 88-95 x 26-28 µm, Verrucaria-type. Ascospores 1-celled, hyaline, ellipsoid, (23.6-)24-28(-30.2) x (10-)10.4-12.5(-13.7) 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.
