Description: Thallus crustose, generally inconspicuous, immersed to thinly superficial, uneven to warted, continuous to rarely rimose, whitish to grey, sometimes delimited by a dark prothallus. Apothecia common, biatorine, to 1.3 mm across, scattered to crowded, with an initially flat, finally usually convex, red-brown, rustty orange or finally black disc, and a initially thick, finally often excluded, more or less concolorous, smooth to flexuose proper margin (colour of apothecia variable, often darker towards center of discs and with a red tinge towards margin). Proper exciple prosoplectenchymatous; epithecium and hymenium patchily golden-brown to yellow-brown, K+ red, C+ purple, otherwise hymenium colourless, not inspersed with oil droplets, amyloid; paraphyses branched, thickened to c. 3 µm wide at apex; hypothecium colourless. Asci 8-spored, cylindrical-clavate, Teloschistes-type. Ascospores 1-septate, polarilocular, hyaline, very thick-walled at poles, ellipsoid, 13-17 x 7-10 µm, the septum 3-5 µm thick (1/5-1/3 of spore length). Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-; apothecia K+ red, C+ purple. Chemistry: thallus without lichen substances; apothecia with chlorinated anthraquinones (chrysophanol, chrysophanal and rhein).
Note: a warm-temperate species found mostly on the smooth bark of trees such as Alnus along rivers; apparently much more common in the past and presently extinct over much of its former range. Forms on twigs with small apothecia are practically indistinguishable from Blastenia subathallina. It is included in the Italian red list of epiphytic lichens as “Near-threatened” (Nascimbene & al. 2013c).
