in Roux & al., Catalogue des Lichens et Champignons lichénicoles de France Métropolitaine, 3e éd.: 1290, 2020. Basionym: Lithocia beltraminiana A. Massal. - Symmicta Lich.: 93, 1855.
Synonyms: Verrucaria beltraminiana (A. Massal.) Trevis.
Description: Thallus crustose, episubstratic, areolate, up to 0.3 mm thick, the areoles sharply angular with brown to black side-walls but usually without a black rim, contiguous, flat, 0.2-0.8 mm wide, whitish to bluish grey, dull. Cortex paraplectenchymatous, overlain by an amorphous epinecral layer; algal layer filling most of thallus; medulla white, with a very thin, brownish basal layer. Perithecia black, numerous, marginal or located between the areoles, deeply immersed, with slightly projecting, convex apices. Involucrellum appressed to exciple, extending to base-level and more or less incurved beneath, c. 40 µm thick laterally; exciple subglobose, 0.2-0.3 mm across, the wall c. 20 µm thick, darker in upper part; hamathecium of 20-25 µm long 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, rather broadly ellipsoid, 17-22 x 7.5-9(-10) µm. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
