Description: Thallus crustose, continuous or cracked, whitish to grey, smooth, epruinose, sometimes delimited by a white prothallus. Apothecia lecanorine, round to angular, sessile, rarely crowded, 0.8-2.3 mm across with an orange-brown to flesh-coloured, but heavily white-pruinose, flat to slightly convex disc and a rather thin, persistent, prominent, usually not flexuose thalline margin. Thalline exciple with a pseudocortex (the hyphae of the medulla almost reaching the margin) containing crystals which are not readily soluble in K; proper exciple thin, colourless, filled with crystals; epithecium grey-brown, with fine granules; hymenium colourless, 50-80 µm high; paraphyses slightly thickened at apex (up to 2.5 µm) hypothecium colourless. Asci 8-spored, elongate-clavate, very thin-walled, with a K/I+ blue, tall tholus penetrated by a faintly amyloid apical cushion, the wall K/I-, surrounded by a K/I+ blue outer layer, Lecanora-type. Ascospores 1-celled, hyaline, simple, broadly ellipsoid, 10-13(-14) x 5.5-8 µm, the wall <1 µm thick. Photobiont chlorococcoid. Spot tests: thallus K+ yellow, C-; disc of apothecia (pruina) C+ bright lemon yellow; margin of apothecia P+ intensely yellow to orange. Chemistry: thallus with atranorin (major), chloroatranorin (minor), psoromic acid, 2'-0-demethylpsoromic acid (minor); apothecia with sordidone (major).
Note: on smooth bark of isolated trees. The Italian material of the G. carpinea-G. leptyrodes complex still needs revision: here I place all records of specimens similar to G. carpinea, and usually found on base-rich, sun-exposed bark, but with the apothecial margin reacting P+ bright yellow.
