Flora, 67: 405, 1884. Basionym: Biatora sylvestris Arnold - in Hepp, Flora, 42: 152, 1859.
Synonyms: Catillaria sylvestris (Arnold) P. Syd
Distribution: N - Ven, Lomb, Emil (Fariselli & al. 2020), Lig (Giordani & al. 2016). C - Tosc, Marc (Nimis & Tretiach 1999), Mol (Nimis & Tretiach 1999, Caporale & al. 2008), Sar.

Description: Thallus crustose, mostly consisting of small areoles, white to yellowish white. Apothecia 0.3-0.8 mm across, usually sparse, rounded, with a reddish brown to dark brown, flat to finally strongly convex disc, and a very thin, soon excluded thalline margin (with a few algal cells restricted to the lower edges of the apothecium). Exciple very well-developed; epithecium yellowish brown to brown; hymenium colourless or yellowish in upper part, 60-85 µm high; paraphyses numerous, exceeding the number of asci, coherent, not or only slightly swollen at apex. Asci 8-spored, narrowly clavate, with a K/I+ blue tholus and a central non-amyloid area, Bacidia-type. Ascospores 1-septate, hyaline, ellipsoid, thin-walled, 11-16 x 4-7 µm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
Note: a mild-temperate lichen of calcareous substrata, incl. mortar walls; probably more widespread, but never common, closely related to Lecania hutchinsiae.
