Involucrellum 25-30 µm thick, reaching to base-level, adpressed to exciple except at base, in upper part covered with a colourless thalline layer; exciple colourless, thin; hamathecium of periphyses and periphysoids measuring 20-25 x c. 3 µm, interascal filaments absent; hymenial gel hemiamyloid, I+ red (I+ blue at very low concentrations of I), K/I+ blue. Asci 8-spored, clavate, I-, fissitunicate, the wall thickened above, with an ocular chamber, dehiscent by extrusion of an endotunica to form a delicate rostrum, Verrucaria-type. Ascospores 1-celled, hyaline, ellipsoid, c. 20 x 7.5 µm. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
