Kiliasia nordlandica (Th.Fr.) Kistenich, Timdal, Bendiksby & S. Ekman

Taxon, 67: 892, 2018.. Basionym: Toninia nordlandica Th. Fr. - Lichenogr. Scand.: 339, 1874.

Synonyms: Kiliasia nordlandica (Th.Fr.) Kistenich, Timdal, Bendiksby & S.Ekman; Lecidea subrimulosa Nyl.; Toninia nordlandica Th. Fr.; Toninia steineri Poelt & Vězda; Toninia subrimulosa (Nyl.) Zahlbr.

Distribution: N - TAA, Lomb, Piem (TSB s.n.), VA (Piervittori & Isocrono 1999).

Description: Thallus squamulose or subsquamulose, consisting of scattered, to 1 cm wide clusters of up to 2(-3) mm wide squamules/areoles which are rounded to irregularly lobed, convex, pale grey to white, sometimes with a brownish hue, weakly to moderately white-pruinose, smooth or shallowly fissured; lower surface pale brown. Upper cortex 25-60 mm thick, including a thick epinecral layer lacking crystals; algal layer continuous; medulla white, lacking crystals; lower cortex thin, partially absent. Apothecia lecideine, black, epruinose or sometimes faintly pruinose, up to 1(-1.5) mm across, soon becoming convex and immarginate. Proper exciple grey in outer part, colourless within, the pigmented parts K+ and N+ violet, lacking crystals; epithecium grey, K+ and N+ violet; hymenium colourless, 40-60 µm high; paraphyses easily made free, 1.8-2.5 µm thick, the apical cells clavate, up to 8 µm wide, surrounded by a pigmented gel; hypothecium colourless. Asci 8-spored, clavate, surrounded by a gelatinous I+ blue coat, with a well-developed I+ blue tholus with a I+ darker blue tube and a well-developed ocular chamber, Bacidia-type. Ascospores 1-septate, hyaline, ellipsoid, 8.5-13 x 4-5 µm. Pycnidia black, immersed. Conidia filiform. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: thallus without lichen substances; Sedifolia-grey pigment in apothecia.

Note: an arctic-alpine species found on steeply inclined to slightly rain-sheltered seepage tracks of calciferous or basic siliceous rocks, almost always on cyanobacterial colonies, or on thalli of Placynthium, at least when young, mostly in upland areas.
