Flora, 51: 51, 1868.
Synonyms: Lithocia tristis A. Massal.; Lithocia tristis f. deformata A. Massal.; Verrucaria diffracta Anzi; Verrucaria tristis (A. Massal.) Kremp. non Hepp
Description: Thallus crustose, episubstratic, often forming irregular patches, thicker and cracked to minutely areolate in central part, thinner and often continuous in marginal parts, delimited by a dark brown prothallus, the areoles 0.2-0.5 mm wide (fertile ones up to 1 mm), brown to dark brown, often with a grey hue, rarely almost whitish. Cortex 40-50 μm thick, 2-layered, the upper layer of isodiametrical, thin-walled, angular cells, pigmented, the inner layer colourless; algal layer continuous, 50-100 μm thick; medulla poorly developed, without a black basal layer. Perithecia black, half immersed in the thallus, forming shallowly convex to conical-hemispherical projections. Involucrellum thick, often reaching to base-level, otherwise reaching at least the upper half, becoming thicker downwards (from 100-150 μm in the middle to 150-250 μm at base); exciple (0.2-)0.3-0.45 mm across, globose, the wall pale brown to finally (only in old perithecia) brown; hamathecium of c. 20 μm long 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, pyriform to obovate, 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, globose to broadly ellipsoid, 8-10(-14) x 6-9 μm, with a thick wall (up to 1 μm). Pycnidia rare, black. Conidia (6-)8-13 μm long. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
