Description: Thallus foliose, heteromerous and dorsiventral, loosely adnate, fragmentary or forming 3-8(-12) cm wide rosettes. Lobes irregular, 3-8(-10) mm wide, elongate, thin, subrotund at apices, with entire or dissected, rarely ascending margins. Upper surface smooth to slightly foveolate, bluish grey to dark red-brown when dry, much darker when wet, epruinose, with brownish, irregular, marginal soralia which later expand over the surface, the soredia usually corticate; lower surface corticate, pale brown, tomentose, smooth to rugulose. Upper and lower cortex pseudoparenchymatous; medulla white. Apothecia very rare, immersed on lower surface at tips of lobes, orbicular, up to 8 mm diam., with a light brown disc and a prominent margin with a usually sorediate thalloid rim. Asci 8-spored, fissitunicate, the thickened apex with a K/I+ blue ring, Peltigera-type. Ascospores subfusiform, 3-septate, pale brown, thick-walled, 17-20 x 5-7 µm. Pycnidia rare, marginal, immersed, punctiform. Conidia bacilliform, 4-5 x 1-2 µm. Photobiont cyanobacterial (Nostoc, the cells not in long chains). Spot tests: upper cortex K-, C-, KC-, P-; medulla K- or K+ pale yellow. Chemistry: upper cortex with an unknown brown pigment; medulla with the following hopane triterpenoids: T2 (15α-acetoxyhopan-22-ol; dolichorrhizin), T3 (hopane-6α,22-diol; zeorin), and T5 (hopane-15α,22-diol).
Note: a cool-temperate to circumboreal-montane lichen found on bark, epiphytic mosses, basic siliceous rocks and soil in humid and sheltered situations, mostly in upland areas. The cryptic species N. orvoi Timdal et al., apparently more widespread in Northern Europe and hardly distinguishable from N. parile morphologically (but with a different chemistry), has been recently reported from Switzerland (Timdal & al. 2020).
Growth form: Foliose, broad lobed
Substrata: rocks, bark, soil, terricolous mosses, and plant debris
Photobiont: cyanobacteria, filamentous (e.g. Nostoc, Scytonema)
Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)
Most common in areas with a humid-warm climate (e.g. most of Tyrrenian Italy)
