Perithecia black, hemispherically projecting, up to 0.25 mm across. Involucrellum adpressed to exciple, reaching down for c. 1/3 of the perithecium; hamathecium of periphyses and slender, branched periphysoids, interascal filaments absent; hymenial gel I+ red, K/I+ blue. Asci 8-spored, clavate, K/I-, fissitunicate, the wall thickened above, with an ocular chamber, dehiscent by extrusion of an endotunica to form a delicate rostrum.
