Description: Thallus crustose, episubstratic, continuous to verrucose, usually up to 1.5 mm thick, whitish to yellowish grey, delimited by a dark prothallus. Apothecia common, lecideine, black (brown in old or damaged specimens), sessile, 0.7-1.2 mm across, with a flat to finally convex disc and a smooth to flexuose, often shiny, finally excluded proper margin. Proper exciple up to 0.1 mm thick, blue-green in outer part, colourless within, without crystals; epithecium blackish green, bluish green to dull grey-blue, rarely olive, often with crystals; hymenium colourless, 60-70(-100) µm high, not inspersed with oil droplets; paraphyses easily made free in K, simple, rarely anastomosing or branched in upper part, not capitate; hypothecium reddish brown to (rarely) yellowish brown. Asci 8-spored, clavate, with an intensely I+ blue tholus penetrated by a weakly amyloid, broadly cylindrical axial mass, and a poorly developed ocular chamber, Lecidella-type. Ascospores 1-celled, hyaline, broadly ellipsoid to ellipsoid, 7-16 x 4.5-10 µm, thick-walled. Pycnidia dark, globose, immersed. Conidia thread-like, more or less curved. Photobiont chlorococcoid. Spot tests: thallus K+ yellow, C- or C+ orange, KC- or KC+ yellow-orange, P-, UV-. Chemistry: 2,5,7-trichloro-3-O-methylnorlichexanthone, 3-O-methylasemone, 3-O-methylthiophanic acid, 5,7-di chloro-3-O-methylnorlichexanthone, atranorin, isoarthothelin, and thiophanic acid.
Note: Often considered as a variety or a form of L. elaeochroma, this species proved to form a monophyletic clade in the molecular analysis by Zhao & al. (2015). The negative reactions of the thallus to C and KC cannot be considered as a discriminant character (see Knoph & Leuckert 2004), and samples with negative reactions could prove to belong to the chemically different L. turgidula. Most Italian records are unreliable.
