Description: Thallus foliose, heteromerous and dorsiventral, broad-lobed, loosely attached, forming 5-25(-30) cm wide rosettes. Lobes elongate, concave, contiguous1.5-3(-5) cm broad, up to 10 cm long, usually obtuse to boat-shaped, with ascending, entire to crenate margins. Upper surface grey to greenish-grey when dry, bright green when wet, smooth, with c. 1 mm wide, numerous, scattered, dark grey, warted cephalodia containing Nostoc, the marginal parts minutely erect-tomentose. Lower surface tomentose, whitish in marginal parts, dark brown to blackish in central parts, with well-distinct, reticulate, brown to black veins and pale to dark, separate, simple to tufted, up to 5 mm long rhizines. Upper cortex pseudoparenchymatous; medulla white; lower cortex absent. Apothecia rare, saddle-shaped, terminal, brown, the cortex on the lower side disrupted into small green patches. Paraphyses simple, distinctly thickened in upper part. Asci 8-spored, fissitunicate, the thickened apex with a K/I+ blue ring, Peltigera-type. Ascospores 3-7-septate, hyaline to pale brown at maturity, acicular, thin-walled, 50-70(-80) x 4-6 μm. Photobiont chlorococcoid (Coccomyxa), cephalodia with Nostoc. Spot tests: K-, C-, KC-, P-, UV-, or medulla rarely faintly C+ and KC+ pink. Chemistry: tenuiorin, methyl gyrophorate and triterpenoids, sometimes with low amounts of gyrophoric acid in the medulla.
Note: this is the vicariant of P. aphthosa on more or less calcareous substrata in upland areas, most common in the beech belt of the Alps, to be looked for further throughout the Apennines.
Growth form: Foliose, broad lobed
Substrata: soil, terricolous mosses, and plant debris
Photobiont: green algae other than Trentepohlia (primary); cyanobacteria, filamentous (e.g. Nostoc, Scytonema) (secundary, e.g. in cephalodia)
Reproductive strategy: mainly sexual
