Circinaria cupreogrisea (Th. Fr.) A. Nordin, Savić & Tibell
Mycologia, 102: 1346, 2010. Basionym: Lecanora cupreogrisea Th. Fr. - Lichenogr. Scand., 1: 278, 1871.
Synonyms: Aspicilia cupreogrisea (Th. Fr.) Hue; Aspicilia mastoidea (Wedd.) Maheu & A. Gillet
Distribution: N - VA (Piervittori & Isocrono 1999). C - Sar (B-36502)
Description: Thallus crustose, episubstratic, rimose-areolate, with an undulate-verrucose surface, pale to dark grey or brownish grey. Apothecia cryptolecanorine-aspicilioid, 0.5-1 mm across, immersed in the areoles, irregular in outline, with a concave to flat, black disc, and a thin, persistent thalline margin. Proper exciple poorly developed, colourless; epithecium olive-brown, N+ green; hymenium colourless, 120-150 µm high, I+ blue; paraphyses not or slightly branched and anastomosing, submoniliform in upper part; hypothecium colourless. Asci 8-spored, clavate, the thin outer coat K/I+ blue, the wall and apical dome K/I-. Ascospores 1-celled, hyaline, ellipsoid, 25-30 x 12-18 µm. Pycnidia black, semi-immersed. Conidia bacilliform, 6-7 x c. 1 µm. Photobiont chlorococcoid. Spot tests: cortex K+ yellow then red (very rarely K- or K+ persistently yellow), C-, KC-, P-; medulla K-. Chemistry: cortex with norstictic acid, very rarely with stictic acid or without lichen substances.
Note: on siliceous rocks in the mountains; perhaps more widespread in the Alps and especially in the high Mediterranean mountains. The species, which is doubtfully distinct from Aspiciliella cupreoglauca, and probably belongs to Aspiciliella.
