Perithecia black, 2/3 to completely immersed in the thallus, 0.35-0.5(-0.6) mm across, not covered by thallus. Involucrellum absent, or scarcely visible as a structure separated from exciple; exciple with a thick, pale brown outer layer throughout; hamathecium of periphyses and periphysoids, interascal filaments absent; hymenial gel I+ red, K/I+ blue. Asci 8-spored, clavate, K/I-, fissitunicate, the wall thickened above, with a broad ocular chamber, dehiscent by extrusion of an endotunica to form a delicate rostrum.
