Verrucaria saprophila (A. Massal.) Trevis.
Consp. Verruc.: 8, 1860. Basionym: Amphoridium saprophilum A. Massal. - Symmicta Lich.: 79, 1855.
Synonyms: Thelidium saprophilum (A. Massal.) Servít
Description: Thallus crustose, endosubstratic to hemiendosubstratic, continuous, whitish to pale grey, often delimited by black lines. Perithecia black, bottle-shaped, immersed in the rock and leaving deep pits when they fall off, the apical, visible part more or less flattened, 0.16-0.25(-0.3) mm wide. Involucrellum absent; exciple bottle-shaped, subglobose and 0.25-0.4(-0.5) mm wide in lower part, with a clear, long apical neck, the wall brown-black throughout; hamathecium of 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, broadly ellipsoid, (24-)30-33(-36) x (12-)13-18(-21) μm. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
