in Cannon & al., Revisions of British and Irish Lichens 11: 76, 2021. Basionym: Lecidea igniarii Nyl. - Flora, 50: 328, 1867.

Description: Thallus crustose, episubstratic, rather thin, pale brown-grey, of discrete or contiguous, convex areoles. Apothecia lecideine, sessile and constricted at base, 0.2-0.4 mm across, with a flat to slightly convex, black disc and a black (in upper part) to pale yellow-brown (in lower part), persistent proper margin. Proper exciple c. 35 μm wide laterally, without crystals, strongly developed below the hypothecium, the outermost part dark brown green (in upper part) to dirty brown or colourless (in lower part), formed by radiating hyphae with cylindrical lumina, the inner part more or less colourless, of narrow, intricately intertwined and richly branched hyphae; epithecium blue-green or green, K- or partly K+ purplish, N+ purple with the formation of blue crystals; hymenium colourless in lower part, 40-50 μm high; paraphyses 1.2-2 μm thick at mid-level, the apical cells clavate, 2.8-4(-5) μm wide, often with an external cap of green pigment; hypothecium very pale brown, K+ purplish, N+ orange-red. Asci 8-spored, cylindrical-clavate, with an amyloid tholus and diffuse non-amyloid apical cushion, and an outer amyloid wall layer. Ascospores 3-septate, hyaline, bacilliform to clavate, slightly curved or a few straight, 12-20 x 2.5-3 μm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: thallus without lichen substances; apothecia with the Bagliettoana-green and Laurocerasi-brown pigments.
