Plant Syst. Evol., 165: 63, 1989.

Synonyms: Umbilicaria grisea f. subpapyria Frey; Umbilicaria hirsuta var. pyrenaica Frey

Distribution: N - VA (Piervittori & Isocrono 1999), Emil (Fariselli & al. 2020). C - Tosc, Sar (Narui & al. 1996, Vězda Lich. Sel. Exs. 2400: Schumm 2025). S - Cal (Codogno 1995, Puntillo 1996, Hafellner 2021).

Description: Thallus foliose, umbilicate, heteromerous, dorsiventral, monophyllous, attached by a central holdfast, rather thick and rigid, up to 10(-15) cm in diam. Upper surface ochraceous grey to pale grey-brown, dull, finely rimose, the marginal parts and sometimes also the central parts with numerous warts giving rise to up to 1(-2) mm wide, darker brown schizidia which tend to fall off leaving scars exposing the medulla; lower surface ochraceous white to pale pinkish brown, usually distinctly areolate, without or rarely with a few pale rhizinomorphs, without trabeculae near the central holdfast and without thalloconidia. Apothecia very rare and incompletely developed, black, gyrodisc. Asci 8-spored, elongate-clavate, thick-walled, the apical dome K/I+ blue, Umbilicaria-type. Ascospores 1-celled, hyaline, ellipsoid, 8-11 x 6-8 μm. Photobiont chlorococcoid. Spot tests: cortex K-, C-, KC-, P-; medulla K-, C+ red, KC+ red, P-. Chemistry: medulla with gyrophoric acid.

Note: on steeply inclined to rain-sheltered surfaces of siliceous rocks, ecologically intermediate between U. grisea and U. deusta, ranging from the Alps to the mountains of Calabria.
