Orphniospora moriopsis (A. Massal.) D. Hawksw.

Lichenologist, 14: 135, 1982. Basionym: Catolechia moriopsis A. Massal. - Ric. Auton. Lich. Crost.: 85, 1852.
Synonyms: Buellia atrata (Sm.) Anzi; Buellia bahusiensis Degel. nom. nud.; Buellia coracina Körb.; Buellia moriopsis (A. Massal.) Th. Fr.; Buellia subtenebrosa Malme; Orphniospora atrata (Sm.) Poelt
Distribution: N - Frl (Tretiach & Hafellner 2000), TAA (Nascimbene & al. 2022), Lomb (Lazzarin 2000b), Piem (Isocrono & al. 2003, 2004).
Description: Thallus crustose, episubstratic, areolate, pale to dark grey or brownish grey, delimited by a conspicuous black prothallus, forming up to 6 cm wide patches. Areoles angular to rounded, flat to convex, 0.3-1 mm wide. Cortex with olive-grey-pigmented outer cells, overlain with an epinecral layer; medulla brownish, weakly I+ blue. Apothecia lecideine, black, sessile, slightly constricted at base, with a flat to slightly convex, epruinose disc, and a thin, usually persistent but sometimes finally excluded proper margin. Proper exciple 35-75 µm wide laterally, expanding to 60-85 µm in upper part, grey to greenish brown in outer part, dark brown within; epithecium dark green, K+ intensifying green, N+ reddish; hymenium colourless to pale reddish brown, not inspersed with oil droplets, 60-110 µm high, I+ blue; paraphyses simple to sparingly branched in upper part, occasionally anastomosing, 1.5-2 µm thick at base, the apical cells slightly swollen and 3-4 µm wide, without a dark cap; hypothecium dark brown, 200-600 µm high, K+ purplish. Asci 8-spored, clavate, tapering at apex into a narrow apical dome, not or weakly I+ blue but ascus apex surmounted with a strongly K/I+ blue cap. Ascospores 1-celled, but appearing 1-septate due to a thickening of the wall in central part, at first hyaline, then soon dark brown, ellipsoid, thick-walled, 10-18 x 6-10 µm. Pycnidia black, immersed in the thallus. Conidia bacilliform, 3-4 x c. 1 µm. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
Note: an arctic-alpine circumpolar lichen found on inclined surfaces of hard siliceous rocks in cold habitats near or above treeline; probably restricted to the Alps in Italy. The record reported by Ricciardi & al. (2000) from Campania, at low elevation, is not accepted here.
