in Vondrák & al., J. Syst. Evol. 58, 3: , 318, 2019.

Distribution: C - Sar (Vondrák & al. 2020). S - Cal (Nascimbene & al. 2021).
Description: Thallus crustose, episubstratic, grey, up to 150 μm thick when young, but old thalli with up to 800 μm thick, convex to bullate areoles, often with a black hypothallus visible among the areoles and forming a black layer in the medulla, delimited by a conspicuous, black prothalline line. Apothecia biatorine/zeorine, 0.7-1 mm across, with a red disc and an often blackened proper margin. Proper exciple prosoplectenchymatous, the outer part often blackened, C+ purple; epithecium orange-brown, K+ red, C-; hymenium colourless, not inspersed with oil droplets; paraphyses simple or sparingly branched and anastomosing, 1.5-3 μm thick in lower part, the apical cells usually wider; hypothecium colourless. Asci 8-spored, clavate, functionally unitunicate, apically thickened with a broad internal beak, the inner part of apex and external cap I+ blue, Teloschistes-type. Ascospores 2-celled, polarilocular, hyaline, ellipsoid, (10-)12-14(-15) x 6-7 µm, the equatorial thickening (“septum”) c. 5 µm. Pycnidia dark grey. Conidia bacilliform, rarely narrowly ellipsoid, 3-5 x 1-1.5 μm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, N+ violet in section; apothecia K+ red, the exciple C+ purple. Chemistry: non-chlorinated anthraquinones in apothecial disc (C-), chlorinated anthraquinones in exciple (C+ purple); thallus without anthraquinones; the Cinereorufa-green pigment (K-, N+ violet in section) forms black patches in thallus, apothecia and pycnidia and often expands into medullary tissue, forming a black hypothallus. For further details see Vondrák & al. (2020).Note: A recently-described species of siliceous rocks in the Mediterranean mountains (Gennargentu, Aspromonte). The records from Calabria (Aspromonte) were cited by Nimis (1993: 167) under B. festivella.
