Pyrenula nitidella (Schaer.) Müll. Arg.
in Engler, Bot. Jahrb., 6: 414, 1885. Basionym: Verrucaria nitida var. nitidella Flörke ex Schaer. - Lich. Helv. Spicil., 2: 58, 1826.
Synonyms: Bunodea nitida var. nitidella (Schaer.) Beltr.; Pyrenula nitida var. dermatodes (Borrer) Trevis.; Pyrenula nitida var. nitidella (Schaer.) Schaer.
Description: Thallus crustose, more or less immersed in the bark, continuous, smooth, olive-brown to pale brown, often with scattered, whitish, punctiform pseudocyphellae. Perithecia black, 0.2-0.35 mm across, numerous, hemispherical to broadly conical, morly immered in the thallus or forming very low projections. Involucrellum closely adhering to the exciple, which appears dark brown throughout, with colourless crystals of calcium oxalates that are insoluble in K; hymenium colourless, not inspersed with oil droplets, the part adjacent to exciple with brown-orange crystals of anthraquinones reacting K+ red (releasing a red solution); hamathecium of branched and anastomosed periphysoids, later substituted by more or less unbranched paraphyses; ostiole with periphyses. Asci 8-spored, narrowly cylindrical, long-stalked, bitunicate, with tholus, thickened at apex with an internal apical beak, non-amyloid. Ascospores 3-septate, brown, thick-walled, narrowly ellipsoid, with diamond-shaped locules, (20-)22-26(-28) x (8-)8.5-11(-12) μm. Photobiont trentepohlioid. Spot tests: thallus: K- or K+ yellow to red-orange around the perithecia, C-, KC-, P-, UV-. Chemistry: anthraquinones in perithecia and sometimes in thallus.
