Taxon, 53, 4: 966, 2004.. Basionym: Parmelia prolixa var. attica Leuckert, Poelt & B. Schwarz - in Vězda, Lich. Sel. Exs. 43: 1069, 1972.
Synonyms: Neofuscelia attica (Leuckert, Poelt & B. Schwarz) Essl.; Parmelia attica (Leuckert, Poelt & B. Schwarz) Essl.
Distribution:
Description: Thallus foliose, heteromerous, dorsiventral, forming 5-12 cm wide rosettes, the lobes appressed, 0.5-3 mm wide, flat, wrinkled and contorted in older parts, smooth or with a faint network of ridges, the upper surface dark brown, matt or glossy at tips, the lower surface black, sometimes brown at margins, with simple, black rhizines. Upper cortex paraplectenchymatous, brown, with a pored epicortex, the cell walls with Xanthoparmelia-type lichenan; medulla white; lower cortex paraplectenchymatous. Apothecia rather rare, lecanorine, sessile to subpedicellate, 1-1.5(-2.5) mm across, with a slightly concave to flat, dark brown disc and a thin, persistent, smooth thalline margin. Epithecium orange-brown; hymenium colourless; paraphyses c. 2.5 μm thick at mid-level, the apical cells up to 3.5 μm wide; 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. Pycnidia laminal, black, globose, the wall mostly colourless, brown around the ostiole. Conidia straight, fusiform or bifusiform. Photobiont chlorococcoid. Spot tests: upper cortex K-, C+ blue-green, P-, UV-, N+ blue-green; medulla K+ yellow turning red-orange, C-, KC+ faintly orange in upper part, KC- or KC+ fleeting red, P+ yellow-orange, UV+ white. Chemistry: medulla with norstictic acid (major), alectoronic acid, and an unidentified fatty acid (minor).
Note: a species growing on siliceous, sometimes weakly calciferous rocks in sunny sites, known from Greece, Cyprus and Turkey; to be looked for in Mediterranean Italy.
