Lichenologist, 46: 29, 2014. Basionym: Biatora ahlesii Körb. - Parerga Lichenol.: 161, 1860.

Synonyms: Biatora valentior (Nyl.) Walt. Watson; Lecidea ahlesii (Körb.) Nyl.; Lecidea valentior Nyl.

Distribution: C - Tosc.

Description: Thallus crustose, episubstratic, continuous or rimose, more or less glossy, pale grey or grey-green, without a distinct prothallus. Medulla white, I-. Apothecia lecideine, 0.3-0.7(-1.2) mm across, sessile, reddish brown to brown-black, with a concave to slightly convex disc and a raised, persistent proper margin. Proper exciple dark reddish brown in inner part, pale reddish brown to colourless in outer part; epithecium colourless or brownish, K-; hymenium colourless, but usually inspersed with blue-violet granules reacting K+ green, 65-90 µm high; paraphyses simple or sparingly branched and anastomosing in upper part, c. 1.5 µm thick at mid-level, the apical cells up to 3 µm wide, without a dark cap; hypothecium dark reddish brown, often with blue-violet granules. Asci 8-spored, clavate, with a I+ blue tholus and an internal, darker I+ tubular structure, the external gel I+ faintly blue, Porpidia-type. Ascospores 1-celled, hyaline, ellipsoid, 12-17.5 x (4-)5-7(-9) µm, sometimes with a thin gelatinous coat. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-. Chemistry: thallus without lichen substances.

Note: on periodically inundated siliceous rocks in lowland areas. The record from Italy (see Nimis 1993: 377) is dubious.
