in Navarro-Rosinés & al., Bull. Soc. Linn. Prov., 58: 174, 2007. Basionym: Verrucaria canella Nyl. - Flora, 66: 102, 1883.
Synonyms: Verrucaria aspiciliae Zehetl. non (J. Lahm) Stizenb. nec Vain.; Verrucaria aspiciliicola R. Sant.; Verrucaria glaucina subsp. canella (Nyl.) A.L. Sm.
Description: Thallus crustose, episubstratic, well developed, areolate, 0.25–0.6 mm thick, the areoles angular, flat, constricted at base and separated by deep cracks, 0.2-1 mm wide, pale grey, usually pruinose, the margins and the sides dark brown to black. Cortex poorly defined, paraplectenchymatous, the cell walls with a brown pigment, overlain by an up to 10 μm thick epinecral layer; medulla colourless to patchily dark pigmented. Perithecia black, 1-5 per areole, immersed, the apex flattened to slightly convex, 0.1-0.2 mm across. Involucrellum absent or poorly developed around the ostiole (appearing as a thickening of the exciple); exciple colourless to brown in lower part, dark brown in upper part, the pigmented parts K+ slightly darker or greenish 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 indistinct ocular chamber, Verrucaria-type. Ascospores 1-celled, hyaline, narrowly oblong or ellipsoid, (18.5-)21-27(-30.5) x (6.5-)7.5-9(-10.5) μm, surrounded by a up to 1.2 μm thick gelatinous perispore. Photobiont chlorococcoid. Spot tests: cortex and medulla K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
