Montanelia panniformis (Nyl.) Divakar, A. Crespo, Wedin & Essl.

Am. J. Bot., 99: 2023, 2012. Basionym: Parmelia olivacea var. panniformis Nyl. - Herb. Mus. Fenn.: 83, 1859.
Synonyms: Melanelia panniformis (Nyl.) Essl.; Parmelia crustificans Hilitzer; Parmelia pannariiformis (Lamy) Vain.; Parmelia panniformis (Nyl.) Vain.; Parmelia panniformis var. pulvinata Hillmann
Distribution: N - TAA (Nascimbene 2006c), Lomb, Piem (Morisi & Sereno 1995, Isocrono & al. 2004).
Description: Thallus foliose, heteromerous, dorsiventral, adnate to loosely adnate, usually more or less panniform and sometimes pulvinate, up to 7(-10) cm in diam., the individual thalli sometimes coalescing into larger patches. Primary lobes discrete to imbricate, (0.3-)0.5-1(-1.5) mm wide, mostly flat, the central parts of thallus with crowded, imbricate, spherical to clavate, simple or slightly branched, small (< 1 mm wide) lobules resembling isidia. Upper surface olive-brown to dark brown, smooth to weakly pitted and sometimes slightly pruinose at the periphery, without pseudocyphellae on the primary lobes, sometimes with obscure pseudocyphellae near the ends of lobules. Lower surface brown to black, paler at the periphery; smooth to irregularly wrinkled, with dark, mostly simple rhizines. Upper cortex paraplectenchymatous, with a non-pored epicortex, the cell walls containing isolichenan; medulla white; lower cortex paraplectenchymatous. Apothecia rare, lecanorine, up to 3 mm across, sessile, with a concave to flat disc and a papillate to lobulate thalline margin. Epithecium brown; hymenium and hypothecium colourless. Asci 8-spored, clavate, Lecanora-type. Ascospores 1-celled, hyaline, ellipsoid, 9-11.5 x 4.5-7 µm. Pycnidia common, black, immersed. Conidia thickened at both ends, 4-7 x c. 1 µm. Photobiont chlorococcoid. Spot tests: upper cortex K-, C-, KC-, P-, N-; medulla K-, C-, KC- or rarely KC+ faintly pink, P-. Chemistry: medulla with perlatolic and stenosporic acids (major).
Note: a mainly northern species in Europe found on steeply inclined surfaces of siliceous rocks in upland areas; almost certainly restricted to the Alps in Italy.
Growth form: Foliose, broad lobed
Substrata: rocks
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly asexual, by thallus fragmentation
