Montanelia disjuncta (Erichsen) Divakar, A. Crespo, Wedin & Essl.

Am. J. Bot., 99: 2022, 2012. Basionym: Parmelia disjuncta Erichsen - Ann. Mycol., 37: 78, 1939.

Synonyms: Melanelia disjuncta (Erichsen) Essl.; Melanelia granulosa Essl.; Parmelia granulosa Lynge nom. illegit.; Parmelia granulosula Oxner; Parmelia sorediata var. coralloidea Lynge

Distribution: N - Ven, TAA (Nascimbene 2006c), Lomb (Nascimbene 2006), Piem (Morisi & Sereno 1995), VA (Matteucci & al. 2015c). C - Tosc (TSB 33883), Laz (TSB 31330), Sar.

Description: Thallus foliose, heteromerous, dorsiventral, closely adnate, 3-5 cm, rarely up to 6(-9) cm in diam., sorediate. Lobes contiguous or becoming imbricate, (0.3-)0.8-1(-2) mm wide, usually flat, often broader and pitted at tips. Upper surface dark olive-brown to blackish, paler olive-brown in shade-forms, smooth to rugulose and/or warted in central, older parts, frequently shiny, especially near the periphery, with usually poorly evident, mostly submarginal, punctiform to slightly elongated pseudocyphellae. Soredia granular to isidioid, dark grey to black (abraded soredia white), arranged in punctiform to capitate, sometimes eroded and crateriform, laminal and submarginal soralia partly arising from pseudocyphellae. Lower surface dark brown to black, 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(-5.5) mm across, sessile or short-stipitate, with a concave to flat disc, and an usually sorediate and pseudocyphellate thalline margin. Epithecium brown; hymenium and hypothecium colourless. Asci 8-spored, clavate, Lecanora-type. Ascospores 1-celled, hyaline, ellipsoid, 9-12.5 x 5-7 µm. Pycnidia rare, mostly laminal, immersed. Conidia thickened at both ends, 6-7.5 x 1 µm. Photobiont chlorococcoid. Spot tests: upper cortex K-, C-, KC-, P-, N-; medulla K-, C -, KC- or rarely KC+ very faintly pink, P-, UV+ white. Chemistry: perlatolic and stenosporic acids (both major).

Note: a widespread lichen of dry-cool areas found on steeply inclined surfaces of siliceous rocks in upland areas; most frequent, but generally not common, in the Alps, very rare in the high Mediterranean mountains.
