Svensk Bot. Tidskr., 17: 94, 1923. Basionym: Biatora turfosa A. Massal. - Ric. Auton. Lich. Crost.: 128, 1852.

Synonyms: Lecidea turfosa (A. Massal.) Jatta; Lecidea verrucula (Norman) Th. Fr.; Lecidella verrucula (Norman) Stein; Micarea verrucula (Norman) Hedl.; Oedemocarpus turfosus (A. Massal.) Trevis.

Distribution: N - Ven, TAA. C - Tosc, Abr.

Description: Thallus crustose, episubstratic, continuous, blackish grey to brown-black, subgelatinous when wet, up to 70 μm thick, forming up to 3-5 cm wide patches, the outer hyphae with a dark green pigment reacting K-, N+ red. Apothecia micareoid, usually numerous and often confluent, 0.1-0.3(-0.4) mm across, black to rarely dark red-brown, with a convex to subglobose disc, without a distinct proper margin. Proper exciple poorly developed but usually visible in very young apothecia, reddish brown, of radiating, branched and anastomosing hyphae; epithecium and upper part of hymenium blue-green, K-, N+ red; hymenium 30-50 mm high, greenish in upper part, olivaceous-brown, fuscous brown or orange-brown in lower part; paraphyses numerous, branched and anastomosing, the walls in upper part olive-black to sordid green, surrounded by the dark olivaceous or aeruginose incrusted gel-matrix, 1.2-1.5(-2) μm thick at mid-level, the upper cells to 3.5 μm wide; hypothecium scarcely differentiated from the hymenium, mottled reddish brown, 60-140 μm high, K-, N- or N+ orange-brown. Asci 8-spored, clavate to cylindrical-clavate, with a K/I+ pale blue apical dome with a dark blue tubular structure, 35-45 x 10-12 μm. Ascospores (0-)1(-3)-septate, oblong-ellipsoid to spindle-shaped, sometimes slightly curved, (10-)12-21(-25) x (3.5-)4-5(-7) μm. Pycnidia immersed, inconspicuous, to 0.04 mm across, the wall sordid green, K-, N+ red. Microconidia cylindrical, 3.5-4.5 x c. μm. Photobiont micareoid, the cells 4-7 μm wide. Spot tests: thallus and apothecia K-, C-, KC-, P-, UV-. Chemistry. without lichen substances.

Note: a circumboreal-montane species found on acid peaty soil, terricolous bryophytes, more rarely on rotting wood in upland areas, reported from the Eastern Alps and the Northern-Central Apennines. Records from Central Italy, although not impossible (Nimis 1993: 437), require confirmation.
