Lecania koerberiana J. Lahm
in Körber, Parerga Lichenol.: 68, 1859.
Synonyms: Lecania opuntiae Bagl.
Description: Thallus crustose, endosubstratic to thinly episubstratic, farinose, whitish grey to pale grey. Apothecia lecanorine, immersed to adnate, 0.3-0.6 mm across, with a reddish brown to blackish, epruinose disc and a thin, often finally excluded thalline margin. Thalline exciple thin, ecorticate, filled with algae at least in lower part; proper exciple thin; epithecium brownish; hymenium colourless, I+ blue turning reddish; paraphyses weakly coherent, the apical cells to 7 µm wide; hypothecium colourless. Asci 8-spored, clavate, with a K/I+ blue apical dome penetrated by a narrow, K/I- apical cushion surrounded by a narrow, deeply K/I+ blue zone, the wall K/I- but surrounded by an I+ red-brown, K/I+ blue outer layer, the ocular chamber relatively small, Biatora-type. Ascospores 3-septate, usually not constricted at septa, hyaline, narrowly ellipsoid, straight or (mostly) slightly curved, 12-15 x 4-5 µm, without a gelatinous perispore. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
