in Poelt & Vezda, Bibl. Lichenol., 16: 364, 1981. Basionym: Lecidea xanthococca subsp. sorophora Vain. - Acta Soc. Fauna Fl. Fenn., 57, 2: 237, 1834.
Synonyms: Hypocenomyce sorophora (Vain.) P. James & Poelt; Lecidea giselae Zahlbr.
Description: Thallus crustose, endo- to episubstratic, areolate, the areoles pale grey to yellowish brown, dull, up to 0.5(-1) mm wide, adnate, weakly convex; soredia bursting from apices or from margins of the areoles, yellowish brown, diffuse, farinose. Cortex up to 15 µm thick, of thin-walled hyphae. Apothecia rare, lecideine, up to 0.6 (-0.8) mm across, with a black, flat to weakly convex, epruinose, egyrose disc and a prominent, entire or slightly flexuose proper margin. Proper exciple of closely conglutinated hyphae, black in outer part, brown within, K+ violet, N-; epithecium green to greenish brown, not containing crystals, K+ violet, N+ violet; hymenium colourless, 55-70 µm high; paraphyses sparingly branched and anastomosing, the apical cells hardly swollen; hypothecium brown. Asci 8-spored, broadly clavate, with a well developed, amyloid tholus containing an ocular chamber and a broad axial mass, Lecanora-type. Ascospores 1-celled, hyaline, broadly to narrowly ellipsoid, 6-9 x 2.5-4.5 µm. Pycnidia sessile, black, up to 0.22 mm across, with a dirty green wall reacting K-, N+ violet. Conidia ellipsoid to shortly bacilliform, 3.5-5 x 1.5-2.7 µm. Spot tests: K+ brownish yellow, C+ red, KC+ red, P+ yellow, UV-. Chemistry: alectorialic acid and an unknown substance.
