Synonyms: Peltigera canina f. nitens Anders; Peltigera degenii f. nitens (Anders) Oxner; Peltigera degenii var. nitens (Anders) Trass; Peltigera nitens (Anders) Gyeln.; Peltigera polydactylon var. submembranacea Nyl.; Peltigera praetextata var. nitens (Anders) Szatala; Peltigera virescens (J. Steiner) Gyeln.
Description: Thallus foliose, broad-lobed, heteromerous and dorsiventral, bluish grey when dry, blackish when wet, loosely attached, forming up to 12(-20) cm wide rosettes. Lobes elongate, flattened, contiguous, rounded at tips, 0.5-1(-1.5) cm broad, 2-5 cm long, with a bluish grey, glabrous, glossy, shiny, smooth to weakly wrinkled upper surface, the margins often up-turned, sometimes phyllidiate. Lower surface whitish near margins, pale brown in central parts, with whitish, raised veins becoming pale brown in central parts, and pale, mostly simple, up to 5-7 mm long rhizines. Upper cortex pseudoparenchymatous; medulla white; lower cortex absent. Apothecia frequent on up-turned short lobes, saddle-shaped, pale brown, 4-9 mm across. Paraphyses simple, distinctly thickened above. Asci 8-spored, fissitunicate, the thickened apex with a K/I+ blue ring, Peltigera-type. Ascospores 3-5-septate, hyaline turning pale brown at maturity, acicular, thin-walled, (40-)45-60(-68) x 2.5-5 μm. Photobiont cyanobacterial (Nostoc, the cells not in long chains). Spot tests: cortex and medulla K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
