Thalloidima tauricum Szatala
Borbasia, 4: 79, 1942.
Synonyms: Toninia clemens H. Baumg. nom. inval.; Toninia schafeevii Tomin; Toninia taurica (Szatala) Oxner
Description: Thallus squamulose, olivaceous brown, epruinose, somehow glossy, with regular, evident fissures in the cortex, the squamules 2-3(-4) mm wide, contiguous to imbricate, orbicular or irregularly lobed, convex to bullate; lower surface pale brown to black. Upper cortex 80-200 μm thick, including an up to 150 μm thick epinecral layer, lacking crystals; algal layer continuous; medulla white, lacking crystals; lower cortex thinner than the upper one, often without an epinecral layer. Apothecia frequent, lecideine, sessile, strongly constricted at base, up to 3 mm across, with a black, but usually densely bluish-pruinose, weakly concave to weakly convex, smooth disc and a distinct, persistent, smooth, faintly pruinose to epruinose proper margin. Proper exciple grey in outer part, colourless within, the pigmented parts K+ and N+ violet; epithecium grey, K+ and N+ violet; hymenium colourless, 60-70 μm high; paraphyses coherent, simple or sparingly branched and anastomosing in upper part, thin-walled, the apical cell distinctly swollen, with a gelatinous pigment cap; hypothecium pale brown to 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, fusiform, 16.5-24.5 x 3-4.5 µm. Pycnidia dark, immersed. Conidia thread-like. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: thallus without lichen substances; apothecia with the Sedifolia-grey pigment.
