Description: Thallus crustose, episubstratic, grey, grey-green or brown-green, continuous to granular-warted, the granules isidia-like, globose or flattened, 40-100 μm wide. Apothecia lecideine, (0.3-)0.4-1(-1.2) mm across, with a purple-brown to black, rarely pink-brown, epruinose, flat to finally convex, sometimes tuberculate disc, and a distinct, paler or darker, finally often excluded proper margin. Proper exciple laterally 59-122 μm wide, without crystals, the inner part red-brown or black-brown, K+ purplish, N+ orange-red, often with a green or blue-green tinge at least in upper part, with a single layer of enlarged cells (up to 8 x 5 μm), the outer rim colourless to pale brown; epithecium greenish to brownish green, scarcely differentiated from the hymenium, K- or K+ purple, N+ purple or orange-red (with or without precipitation of blue crystals); hymenium (45-)55-80(-112) μm high, the lower part colourless except for occasional vertical green streaks, the upper part dirty green to blue-green; paraphyses simple, 1.2-2.4 μm thick at mid-level, the apical cells not swollen or up to 5(-6.5) μm wide; hypothecium dark brown at least in upper part, sometimes with a green-brown tinge. Asci 8-spored, clavate, surrounded by a gelatinous I+ blue coat, with a well-developed I+ blue tholus, an I+ darker blue tube and a well-developed ocular chamber, Bacidia-type. Ascospores (3-)5-13-septate, hyaline, bacilliform, clavate, or acicular, straight to sigmoid, (13-)20-36(-40) x 2.5-3.5(-4) μm. Pycnidia immersed in thallus. Conidia simple, filiform, curved, 10-20 x c. 0.8 μm. Photobiont chlorococcoid, the cells 5-12 μm in diam. Spot tests: thallus and apothecia K-, C-, KC-, P-, UV-. Chemistry: no lichen substances in thallus; apothecia with Bagliettoana-green in epithecium and rim of exciple; Laurocerasi-brown in hypothecium and lateral part of exciple; sometimes a mixture of the two pigments in exciple. Rubella-orange in epithecium, hypothecium and exciple (in albino morphs).Note: a mainly temperate lichen found on the bark of old broad-leaved trees (especially Fagus and Quercus) in open, humid woodlands. This species was treated as Bacidia subincompta by Coppins & Aptroot (2009) and Toniniopsis subincompta by Kistenich & al. (2018), but Ekman (1996) demonstrated that the type of that species belongs to the lichen presently called Bellicidia incompta. All Italian records are provisionally attributed to T. separabilis, but Italian material urgently needs revision, and should be also compared with the very similar and recently-described T. dissimilis Gerasimova & A. Beck, which is known from Turkey and several European countries, including Austria.
