Thallus: to 6 cm diam., closely appressed. Lobes narrow, short, often broader and pitted towards the tips, 0.3- 1 mm wide. Upper surface olive brown to blackish brown, rather shiny. Soralia conspicuous and crowded or diffuse, laminal to submarginal, partly developing from pseudocyphellae, punctiform or capitate; soredia usually blackish; isidia absent; pseudocyphellae present close to the margin, punctifonn to somewhat elongated, whitish or more often rather obscure. Lower surface dark brown to black with simple, concolorous rhizines. Apothecia rare, sessile or shortly stalked, to 5 mm diam. Spores ellipsoid, 9- 12.5 x 5- 7 μm. Pycnidia rare, laminal. Conidia dumbbell-shaped, 6- 7.5 x 1 μm (Westberg & Thell 2011: 140).

Photobiont: Data lacking.

Chemistry: Cortex HNO3-. Medulla C-, K-, KC-, PD-; perlatolic acid, stenosporic acid (Westberg & Thell 2011: 140).

Ecology: Saxicolous on siliceous stones and cliffs in open situations, more frequent in the inland areas, rarely on bark or lignum (Westberg & Thell 2011: 140).

Distribution type: "Fairly common throughout the Nordic countries. Circumboreal in the Northern Hemisphere and also occurring at subalpine-alpine areas in East Africa. The species is easily overlooked and its distribution is therefore still insufficiently known" (Westberg & Thell 2011: 140).

Taxonomy: "Some species in the newly recognized genus Montanelia, such as M. disjuncta and M. sorediata, were found to be non-monophyletic. Additional studies are necessary to clarify the current species delimitation in this group, which is largely based on macromorphological and chemical characters. A detailed investigation evaluating the cryptic diversity in this group is under progress and will be discussed in a forthcoming paper" (Divakar et al. 2012: 2023).

Note: Parmelia disjuncta Erichsen, Ann. Mycol. 37: 78 (1939) „xxx“. Nomen novum für Parmelia sorediata var. coralloidea Lynge, Lich. Novaya Zemlya: 200 (1928).

Der ehemalige Markt Neuhaus ist seit 1972 ein Ortsteil der Stadt Windischeschenbach in der nördlichen Oberpfalz.

Krottensee, formerly a village 1 km east of Neuhaus an der Pegnitz, is now a part of this small town.
