Lecidea hypopta Ach.
Meth. Lich.: 61, 1803.
Synonyms: Biatora hypopta (Ach.) Räsänen; Lecanora hypopta (Ach.) Vain.; Lecanora subintricata var. convexula Arnold
Description: Thallus crustose, white to olivaceous grey, smooth to finely granulose or verrucose, sometimes poorly evident. Apothecia biatorine, 0.2-0.5(-0.7) mm across, broadly adnate, with a strongly convex, brown-black to black disc and a paler, thin, soon excluded margin. Exciple corticate, pale brown in outer part, colourless within, of thin, strongly gelatinized, anastomosing and radiating hyphae, the cortex, especially in the basal part, with many black granules, the medulla without algae or with a few algae at the base only; epithecium bluish-green or reddish brown, often piebald, without crystals; hymenium colourless, (30-)40-50(-60) µm high, I+ blue; paraphyses coherent, the apical cells up to c. 4 µm wide; hypothecium colourless. Asci 8-spored, Micarea-type, the tholus with a thin, I+ dark blue tubular structure. Ascospores 1-celled, hyaline, ellipsoid to narrowly ellipsoid, sometimes slightly curved, (7-)9-12(-13) x (2.5-)3-4(-5) µm. Pycnidia dark, immersed. Conidia curved, 14-18 x 4-5 µm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
