Melanelixia glabra (Schaer.) O. Blanco, A. Crespo, Divakar, Essl., D. Hawksw. & Lumbsch
Mycol. Res., 108: 882, 2004. Basionym: Parmelia olivacea var. corticola f. glabra Schaer. - Lich. Helv. Spicil., 10: 466, 1840.
Synonyms: Melanelia glabra (Schaer.) Essl.; Parmelia glabra (Schaer.) Nyl.; Parmelia olivacea auct. ital. p.p.; Parmelia olivacea var. glabra (Schaer.) Linds.; Parmelia olivacea var. imbricata A. Massal.
Description: Thallus foliose, heteromerous, dorsiventral, broad-lobed, appressed or slightly ascending at the periphery, forming large, up to 11(-15) cm wide, sometimes confluent, orbicular rosettes. Lobes rounded at tips, contiguous to imbricate, 2-5(-8) mm broad, mostly flat, brown, smooth to strongly rugose in central parts, with tiny, hyaline cortical hairs visible at least on some lobe-ends and on apothecial margins (stereo-microscope!); pseudocyphellae inconspicuous, present on warts or ridges, especially on the apothecial margins. Lower surface dark brown to black, often paler at margins, with simple, black rhizines. Upper cortex paraplectenchymatous, with a pored epicortex, the cell walls containing isolichenan; medulla white; lower cortex paraplectenchymatous. Apothecia common, lecanorine, to 1.5(-2) cm across, sessile to shortly stipitate, with an initially strongly concave, then irregularly flattened, brown disc, and a reticulately ridged, often pseudocyphellate margin which nearly always has cortical hairs. Epithecium brown; hymenium and hypothecium colourless. Asci 8-spored, clavate, the K/I+ blue tholus penetrated by a faintly amyloid apical cushion with parallel or diverging flanks, the wall K/I-, surrounded by a K/I+ blue outer layer, Lecanora-type. Ascospores 1-celled, hyaline, ellipsoid to broadly ovoid, 11-15 x 5.5-8(-10) µm. Pycnidia common, immersed. Conidia bacilliform, (6.5-)8-9 x c. 1 µm. Photobiont chlorococcoid. Spot tests: upper cortex K-, C-, KC-, P-, N-; medulla K-, C+ red, KC+ red, P-, UV-. Chemistry: medulla with lecanoric acid.
