Description: Thallus crustose, largely endosubstratic, whitish grey to olive-brown, continuous or slightly fissured, to 0.1 mm thick. Perithecia black, (0.2-)0.3-0.4(-0.5) mm across. Involucrellum dark brown, dimidiate; exciple prosoplectenchymatous, colourless to brownish in upper part; hamathecium of slender, thread-like, 1.5-2 μm thick paraphysoids which are mostly simple, and only rarely branched and anastomosing, except where adjacent to the exciple. Asci 8-spored, cylindrical to narrowly clavate, bitunicate-fissitunicate, shortly stalked at base, with a more or less bilobed foot, the apex thickened into a tholus, with a narrow ocular chamber, I-. Ascospores 1-septate and strongly constricted at septum, hyaline, subfusiform, 18-28 x 3.5-5.5 μm, separating into two part-spores before or during dehiscence of the ascus, the part-spores 9-15 x 3-5.5 μm. Pycnidia often of two types. Macropycnidia black, 0.12-0.2(-0.3) mm across; macroconidia laterally inserted on the conidiogenous cell, the point of insertion thus subterminal, 1-septate, with a gelatinous appendage, 8-11.5 x (2.5-)3-4.5 μm, each cell with a large, persistent oil droplet. Micropycnidia similar to macropycnidia but 0.1-0.18 mm across; microconidia fusiform to subfusiform, 2.5-5 x 1-2 μm. Photobiont trentepohlioid. Spot tests: thallus K-, C-, KC-, P-. Chemistry: thallus without lichen substances.
Note: a mild-temperate to Mediterranean-Atlantic lichen found on bark of broad-leaved trees in open woodlands (e.g. on Quercus, Castanea); probably more widespread, especially in Southern Italy, but not common. The record of Strigula taylorii s.lat. from Sicily by Nimis & al. (1994) refers to this species.
