Distribution: N - Piem (TSB 34093).

Description: Thallus crustose, episubstratic, areolate-subsquamulose, forming 3-7(-15) mm wide patches on the thalli of Lecidea paupercula, without a distinct prothallus. Areoles subpeltate, slightly concave to flat, smooth, yellowish brown to blackish brown, 0.2-0.7(-1.2) mm across, 0.1-0.4 mm thick, each one surrounded by a 0.1-0.2 mm wide, bluish black margin formed by 7-9 µm thick, warty, branched, 5-8 µm wide hyphae producing thalloconidia. Thalloconidia (1-)2-3-celled, 10-12 x c. 7 µm, with irregularly arranged rounded, warty, bluish black cells, N+ dark purple. Apothecia extremely rare, lecanorine, adnate, with a brown disc and a thin, not prominent thalline margin. Exciple brown, pseudoparenchymatous; hymenium colourless; paraphyses coherent, simple or sparingly branched, thick, the apical cells slightly swollen; 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, thin-walled, 8-11 x 5-7 µm. Photobiont chlorococcoid. Spot tests: cortex and medulla K-, C-, KC-, P-. Chemistry: stictic, norstictic and cryptostictic acid (mostly in traces).

Note: an arctic-alpine silicicolous species which starts the life-cycle on other lichens (Lecidea paupercula, more rarely Sporastatia and other crustose lichens), more widespread in Scandinavia than in the Alps, where it occurs above treeline. The species does not belong to Protoparmelia s.str.
