Schaereria cinereorufa (Schaer.) Th. Fr.

N. Acta Reg. Soc. Sci. Upsal., ser. 3, 3: 175, 1861. Basionym: Lecidea cinereorufa Schaer. - Lich. Helv. Spicil., 3: 122, 1828.

Synonyms: Lecidea subfurva Nyl.; Psora cinereorufa (Schaer.) Hellb.; Schaereria lugubris (Fr.) Körb.

Distribution: N - Ven, TAA, Piem (Isocrono & al. 2004).

Description: Thallus crustose, episubstratic, areolate; areoles 1-2.5(-3) mm wide, convex, often constricted at base and appearing subsquamulose, contiguous, wrinkled, forming a thick, grey-brown to dark brown, often reddish-tinged crust sometimes delimited by a black prothallus. Apothecia lecideine, black, to 0.5-1.2(-1.5) mm across, closely adnate or almost level with thallus, with a concave disc and a thick, persistent proper margin. Proper exciple dark brown; epithecium bluish green to emerald green, K+ intensifying green; hymenium colourless or greenish, 90-120 μm high; paraphyses rather lax, mostly simple, the apical cell clearly swollen; hypothecium dark orange-brown. Asci 8-spored, cylindrical, thin-walled, with a single wall layer, not thickened apically, only the outermost gelatinous layer K/I+ faintly blue, discharge by splitting of the apex, Schaereria-type. Ascospores 1-celled, hyaline, globose, 7-10 μm in diam., uniseriately arranged in the asci. Pycnidia dark brown, immersed. Conidia bacilliform, 4-6 μm long. Photobiont chlorococcoid. Spot tests; thallus K-, C-, KC-, P-; medulla sometimes C+ and KC+ pink. Chemistry: medulla with gyrophoric acid (often in very low amounts), plus an unknown compound (‘Cinereorufa’ unknown).

Note: an arctic-alpine to boreal-montane, circumpolar species found on inclined to vertical faces of mineral-rich rocks wetted by rain, often near the ground, usually associated with species of Pertusaria; probably restricted to the Alps, where it can reach the nival belt.
