Taxon, 67: 895, 2018.. Basionym: Lecidea bacillifera var. circumspecta Nyl. ex Vain. - Meddeland. Soc. Fauna Fl. Fenn., 10: 22, 1883.
Synonyms: Bacidia circumspecta (Vain.) Malme; Bacidia quercicola (Nyl.) Vain.; Lecidea circumspecta (Vain.) Hedl.
Description: Thallus crustose, continuous, cracked, or of discrete to contiguous, usually convex areoles, whitish, pale grey-green or pale grey-brown. Apothecia lecideine, black, 0.2-1 mm across, with a flat to finally weakly convex disc and an often glossy proper margin. Proper exciple 20-70 µm wide laterally, without crystals, dark purple-brown, K+ intensifying purple in upper part and along the rim, colourless or pale-pigmented within; epithecium blue-green to olive-green, rarely partly purplish brown, with a blue-green (K-, N+ purple, often with blue crystals) and a purplish brown (K+ purple, N+ orange) pigment in various amounts, the former usually prevalent; hymenium colourless, 45-55(-70) µm high; paraphyses simple or forked in upper part, 0.8-1.6 µm thick at mid-level, the apical cells swollen, up to 5 µm wide; hypothecium colourless or pale yellowish brown in upper part. Asci 8-spored, clavate, with an amyloid tholus and diffuse non-amyloid apical cushion, and an outer amyloid wall layer. Ascospores 3-7(-9)-septate, bacilliform to thread-like, straight, (15-)20-35(-45) x (1.5-)2-2.5(-3) µm. Pycnidia half-immersed to almost sessile, bluish or black, the wall with both purple-brown and green pigments. Conidia oblong-cylindrical, 0-1-septate, 7-9 x 1.5-2 µm. Photobiont chlorococcoid, the cells 7-14(-16) µm wide. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: thallus without lichen substances.
