Lobothallia melanaspis (Ach.) Hafellner
Acta Bot. Malacitana, 16, 1: 138, 1991. Basionym: Parmelia melanaspis Ach. - Meth. Lich.: 196, 1803.
Synonyms: Aspicilia melanaspis (Ach.) Poelt & Leuckert; Lecanora melanaspis (Ach.) Ach.
Description: Thallus foliose to subcrustose-placodioid, episubstratic, loosely attached, grey-white to brownish or dark glaucous grey, sometimes darkened at lobe-tips, turning bright green when wet, forming regular to irregular, up to 6 cm wide rosettes. Lobes elongate, radiating, overlapping, several cm long and 0.4-1.3(-1.5) mm wide, mostly convex; lower surface white, erhizinate. Upper cortex paraplectenchymatous, brownish; medulla white, loose, I-. Apothecia lecanorine to 1.8 mm across, at first semi-immersed, then sessile to short-stalked, with a flat to convex, red-brown to brown-black disc, and a prominent, sometimes finally excluded thalline margin. Epithecium reddish brown, N+ green; hymenium colourless, 60-75(-90) μm high; paraphyses weakly branched, submoniliform, the apical cells swollen and c. 3 μm wide; hypothecium colourless, subtended by an algal layer. Asci 8-spored, cylindrical-clavate, the thin outer coat K/I+ blue, the wall and apical dome K/I-. Ascospores 1-celled, hyaline, ellipsoid, 10-13 x (6-)8-10 μm. Pycnidia black, immersed. Conidia hyaline, bacilliform, 4.5-6 x c. 1 μm. Photobiont chlorococcoid. Spot tests: cortex and medulla K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
