Lecidea turgidula Fr.
Sched. Crit., 1: 10, 1824.
Synonyms: Biatora turgidula (Fr.) Nyl.; Lecidea denudata sensu A. Massal.; Lecidea subglomerella Nyl.; Lecidella turgidula (Fr.) Körb.; Oedemocarpus turgidulus (Fr.) Trevis.
Description: Thallus crustose, often poorly developed and inconspicuous, endosubstratic or thinly granular, whitish or olivaceous grey. Apothecia biatorine, black (bluish black when wet), adnate to partly immersed, 0.2-0.6(-0.8) mm across, with an initially flat but soon turning convex, sometimes thinly white-or bluish-pruinose, often uneven disc (especially when young), and a soon excluded proper margin. Proper exciple of coherent, radiating hyphae, dark greenish brown in outer part, colourless within; epithecium olive-black to blue-green, K+ intensifying green, N+ reddish, with minute granules dissolving in K; hymenium with violet, brownish or greenish vertical streaks reacting K+ green, (30-)50-70(-80) µm high, I+ blue; paraphyses sparingly branched and anastomosing, 1-2 µm thick at mid-level, the apical cells not much swollen, but sometimes with a dark brown, to 5 µm wide cap; hypothecium colourless to pale yellowish brown, sometimes orange-brown in upper part. Asci 8-spored, broadly clavate, Bacidia-type. Ascospores 1-celled (rarely a few 1-septate), hyaline, oblong to ellipsoid, 6-10(-14) x 2.5-4.5(-5.5) μm, straight to slightly curved. Pycnidia black, immersed, the wall green-brown, K+ green. Conidia short-bacilliform, arising laterally and terminally, 3-4 x 1.5-1.8 μm. Photobiont chlorococcoid, the cells 12-15 µm wide. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: thallus with placodiolic acid.
