Description: Thallus crustose, endosubstratic, whitish to pale grey, sometimes with a reddish tinge, continuous and without cracks, not delimited by a black prothalline line. Perithecia black, immersed in pits in the rock or in wart-like swellings of the thallus, the apical part 0.4-0.7 mm wide. Involucrellum absent; exciple pear-shaped, 0.5-0.8 mm across, the wall brown throughout, K+ darker brown; hamathecium of periphyses and periphysoids, interascal filaments absent; hymenial gel hemiamyloid, I+ red (I+ blue at very low concentrations of I), K/I+ blue. Asci 8-spored, clavate, I-, fissitunicate, the wall thickened above, with an ocular chamber, dehiscent by extrusion of an endotunica to form a delicate rostrum, Verrucaria-type. Ascospores 1-celled, hyaline, ellipsoid to broadly ellipsoid, (24-)29-35(-42) x (14-)16-21(-24.5) μm, often with a distinct fine ornamentation of short, simple or branched ridges, often with a thin gelatinous perispore. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.

Note: a variable species found on steeply inclined surfaces of compact limestone and dolomite in sheltered situations; restricted to upland areas in Southern Italy, where sometimes it reaches the oromediterranean belt. See also Tretiach & Nascimbene (2006) and the note on V. foveolata.
