Distribution: N - Frl (TSB s.n.), Lomb (Ravera & al. 2022b).

Description: Thallus crustose, episubstratic, areolate and sorediate, forming orbicular, up to 3 cm wide (or more), irregular patches, occasionally confluent with other thalli and covering much wider areas; prothallus very variable, from well-developed and brown-zoned to poorly developed and shiny, rarely indistinct. Areoles greyish green, matt, rounded, convex, up to 0.2 mm wide. Soralia bursting from the apices of the areoles, green, yellow-green or straw-coloured, irregularly rounded, often becoming confluent, especially towards the centre, forming a more or less continuous subleprose crust, the soredia farinose, 20-30 μm in diam., sometimes loosely packed into larger consoredia. Apothecia very rare, lecideine, black, 0.2-0.4 mm across, with a flat disc and a persistent proper margin. Proper exciple brown in outer part, pale brown within, of c. 2 μm wide, evenly thickened, often tortuous hyphae with at least some lumina which are >4 times as long as wide; epithecium brown; hymenium colourless, 50-75 μm high, non-amyloid, inspersed with oil droplets; paraphyses easily becoming free, mostly simple, 1.5-2 μm thick, the apical cells not or only slightly thickened; hypothecium pale brown. Asci 12-16-spored, clavate to broadly clavate, with a non-amyloid wall and a thin and weakly developed tholus in mature asci, K/I+ deep blue. Ascospores 5-6-septate, hyaline, clavate, straight to curved; 22-31(-44) x (1.7-)2-2.5(-3.7) μm. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, soralia UV+ white. Chemistry: perlatolic acid (major), hyperlatolic-, isohyperlatolic- and superlatolic acids (minor or traces).

Note: on smooth bark of deciduous and coniferous trees in cold-humid, open woodlands; perhaps more widespread, but certainly not common. It was included in the Italian red list of epiphytic lichens as “Data Deficient” (Nascimbene & al. 2013c).
