Description: Thallus foliose, heteromerous, dorsiventral, broad-lobed, loosely attached, 3-15(-25) cm diam. Lobes subirregular, slightly imbricate, flattened, 5-15(-20) mm wide, with broadly rounded apices, becoming crenate and dissected with age, often ascending, with usually abundant, black, up to 3 mm long marginal cilia. Upper surface grey with some blackened areas, smooth, faintly maculate, with simple to coralloid, often apically ciliate, laminal and marginal isidia. Lower surface black with a brown naked peripheral zone, centrally with simple, black rhizines. Upper cortex of tightly packed, anticlinally oriented hyphae, with a pored epicortex, the cell walls with lichenan intermediate between the Cetraria- and the Xanthoparmelia-types; medulla white; algal layer continuous; lower cortex prosoplectenchymatous, with rounded and thick-walled cells. Apothecia rare, lecanorine, substipitate, to 8 mm across, with a sparsely isidiate margin and a brown, imperforate disc. Epithecium brownish; hymenium and hypothecium colourless. Asci 8-spored, Lecanora-type. Ascospores 1-celled, hyaline, ellipsoid, 21-31(-35) x 11-18 µm. Pycnidia rare, black, laminal, immersed. Conidia long-bacilliform to thread-like. Photobiont chlorococcoid. Spot tests: upper cortex K+ yellow, C-, KC-, P-; medulla K+ yellow-orange, C-, KC+ yellow-orange, P+ orange, UV-. Chemistry: upper cortex with atranorin and chloroatranorin; medulla with stictic acid (major), constictic acid (minor), and menegazziaic acid (trace) plus other accessory substances.
Note: a cool-temperate lichen found on bark in open humid montane forests, rarely on epilithic bryophytes, exceptionally descending to the submediterranean belt in very humid areas; most common in the Alps, but extending to the mountains of Calabria. Molecular data (Stelate & al. 2022) do not allow to distinguish this species from P. perlatum, which however is sorediate and has a different ecology and altitudinal distribution. It is included in the Italian red list of epiphytic lichens as “Near-threatened” (Nascimbene & al. 2013c).
Growth form: Foliose, broad lobed
Substrata: bark
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly asexual, by isidia, or isidia-like structures (e.g. schizidia)
Most common in areas with a humid-warm climate (e.g. most of Tyrrenian Italy)
