Protoparmelia cupreobadia (Nyl.) Poelt

in Poelt & Leuckert, Nova Hedwigia, 52: 52, 1991. Basionym: Lecanora cupreobadia Nyl. - Bot. Not.: 165, 1853.

Synonyms: Lecanora badia var. cupreobadia (Nyl.) Boistel

Distribution: N - TAA. C - Sar.

Description: Thallus crustose, episubstratic, rimose-areolate to areolate-subsquamulose, copper-brown to dark brown, forming 3-5(-10) cm wide patches, starting the development on the thalli of yellow Rhizocarpon-species, often delimited by a black prothallus, Areoles more or less round to irregularly polygonal, mostly flat, 0.5-1 mm wide, the peripheral ones elongate and slightly radiating, developing on a black hypothallus. Cortex 10-50 µm thick, with a very thick epinecral layer; medulla white, I-. Apothecia lecanorine, round to angular, broadly sessile, 0.5-1.5(-3) mm across, with a brown to brown-black, flat to convex disc, and a smooth, sometimes finally excluded thalline margin. Thalline exciple corticate; proper exciple c. 150 µm thick laterally, not forming a cupula below the hypothecium; epithecium pale brown, c. 15 µm high; hymenium colourless, 40-50(-75) µm high; paraphyses branched, 2-3 µm thick, the apical cells to 5 µm wide; hypothecium colourless. Asci 8-spored, clavate, approaching the Lecanora-type, with a well-developed amyloid tholus and a distinct, non-amyloid axial mass. Ascospores 1-celled, hyaline, ellipsoid to narrowly ellipsoid, (8-)10-17 x 5-7 µm. Pycnidia rare, immersed, dark around the ostiole. Conidia filiform, curved, 20-30(-35) µm long. Photobiont chlorococcoid. Spot tests: K+ yellow turning red (needle-shaped crystals), C-, KC-, P+ orange. Chemistry: cortex with norstictic acid, medulla with additional rangiformic acid.

Note: on gneiss and compact porphyric rocks near and especially above treeline, starting the life-cycle on yellow Rhizocarpon-species, later becoming autonomous; probably more widespread in the Alps. This species does not belong to Protoparmelia s.str.
