Lecanora epibryon var. bryopsora Doppelb. & Poelt
in Poelt, Mitt. bot. Staatss. München, 5: 254, 1964.
Synonyms: Lecanora bryopsora (Doppelb. & Poelt) Hafellner & Türk
Description: Thallus crustose, episubstratic, whitish to pale grey, continuous to warted, sorediate. Soredia granular, whitish to very pale yellowish white, developing in initially discrete, then often confluent soralia. Apothecia rather rare, lecanorine, more or less round, sessile, strongly constricted to almost substipitate, 0.5-1.5 mm across, with a reddish brown, epruinose, often somewhat shiny, mostly flat disc, and a thick, smooth to crenulate-undulate thalline margin. Thalline exciple to 100 µm thick, containing small, irregular crystals visible under polarized light and not dissolving in K; epithecium red-brown, without crystals, sometimes with small oil droplets; hymenium colourless, 60-90 µm high; paraphyses simple or sparingly branched in upper part, 1.5-2 µm thick, the apical cells slightly thickened and to 3.5 µm wide; hypothecium colourless. Asci 8-spored, clavate, very thin-walled, with a K/I+ blue, tall tholus penetrated by a faintly amyloid apical cushion, the wall K/I-, surrounded by a blue outer layer, Lecanora-type. Ascospores 1-celled, hyaline, ellipsoid or narrowly ellipsoid, 12-19 x 6-9.5 µm. Photobiont chlorococcoid. Spot tests: thallus K+ yellow, C-, KC-, P- or P+ slowly and faintly yellow, UV-. Chemistry: atranorin and variable amounts of zeorin.
