Phaeophyscia sciastra (Ach.) Moberg
Symb. Bot. Upsal., 22, 1: 47, 1977. Basionym: Parmelia sciastra Ach. - Meth. Lich. Suppl.: 49, 1803.
Synonyms: Hagenia obscura var. sciastra (Ach.) Bagl. & Carestia; Physcia lithotea auct.; Physcia sciastra (Ach.) Du Rietz
Description: Thallus foliose, heteromerous, dorsiventral, narrow-lobed, closely attached, forming orbicular to irregular, up to 5 cm wide rosettes. Lobes linear and discrete 0.2-0.6(-1) mm broad, flat to irregularly convex, grey to almost black in sun-forms, usually epruinose, sometimes with a whitish epinecral layer in the center, with granular to subcylindrical, darker, pseudocorticate isidia arranged in irregular, short to elongate clusters (sometimes appearing like isidioid soredia). Lower surface black, sometimes paler at lobe ends, with simple, black rhizines. Upper and lower cortex paraplectenchymatous; medulla white. Apothecia rare, lecanorine to 2 mm across, sessile. Epithecium brown; hymenium and hypothecium colourless; paraphyses slender, often forked in upper part, the apical cells clavate, with a thin dark cap. 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-septate, brown, ellipsoid, Physcia-type, (14-)16-22(-24) x 7-12 µm. Pycnidia rare. Conidia ellipsoid, 2-4 x c. 1 µm. Photobiont chlorococcoid. Spot tests: cortex and medulla K-, C_, KC-, P-, UV-. Chemistry: medulla sometimes with terpenoids (traces).
