Description: Thallus foliose, heteromerous, dorsiventral, forming 3-6(-10) cm wide rosettes, sorediate. Lobes 3-7 mm wide, with rounded, ascending margins, grey-green to (rarely) grey-brown, often pruinose al lobe-tips and along margins, with numerous punctiform, white pseudocyphellae; soralia mainly marginal on secondary ascending lobes, elongated, often crescent-shaped, with farinose to granular soredia. Lower surface cream-white at margins, pale brown in central parts, with simple rhizines except at lobe margins. Upper cortex paraplectenchymatous, of 2-6 layers of densely packed cells, with a non-pored epicortex, the cell walls with isolichenan; medulla white; algal layer continuous; lower cortex paraplectenchymatous. Apothecia unknown. Pycnidia rare, laminal, immersed. Conidia unciform to short-filiform, 3-5 x 1 µm. Photobiont chlorococcoid. Spot tests: upper cortex K+ yellow, C-, KC-, P-; medulla and soralia K-, C+ red, KC+ red, P-, UV-. Chemistry: upper cortex with atranorin; medulla and soralia with lecanoric acid.
Note: a recently-resurrected species found on bark of isolated deciduous trees, ecologically intermediate between Xanthorion and Parmelion; to be looked for throughout Italy. European specimens might not be identical with North American material, and deserve further study (see Lendemer & Hodkinson, 2010).
Growth form: Foliose, broad lobed
Substrata: bark
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)
