N. Amer. Fung., 7, 2: 3, 2012. Basionym: Parmelia carneopruinata Zahlbr. - Sber. Akad. Wiss. Wien, Math.-naturw. Kl., Abt. 1, 111: 419, 1902.
Synonyms: Canoparmelia carneopruinata (Zahlbr.) Elix & Hale; Parmelia sbarbaronis B. de Lesd.; Parmotrema carneopruinatum (Zahlbr.) D. Hawksw.; Pseudoparmelia carneopruinata (Zahlbr.) Hale
Distribution: N - Lig (Watson 2014).
Description: Thallus foliose, closely adnate, sorediate, 2-5 cm across. Lobes sublinear, 1-3 mm wide, rounded at apices, grey, emaculate, reticulately ridged, wrinkled and cracked, fragile, sometimes pruinose, with laminal soralia developing along the margins of cracks; soredia yellowish orange, granular. Medulla white, yellow to yellowish orange below soralia. Lower surface black in central parts, with simple, black, short rhizines; marginal parts brown, erhizinate, shomehow shiny. Apothecia extremely rare, lecanorine. Asci 8-spored, Lecanora-type. Ascospores 1-celled, hyaline, ellipsoid. Photobiont chlorococcoid. Spot tests: upper cortex K+ yellow, C-, KC-, P+ yellow; medulla K+ yellow-red, C-, KC-, P+ orange. Chemistry: chloroatranorin, atranorin, stictic, constictic and cryptostictic acids.
Note: this species is very closely related to C. crozalsiana, and a more detailed study is needed to ascertain whether the two species should be retained as distinct.
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)
Most common in areas with a humid-warm climate (e.g. most of Tyrrenian Italy)
