Anamorph: not known. Teleomorph: ascomata immersed in and becoming erumpent from bleached decorticated wood, round or broadly elliptical in outline, the overlying substrate barely raised above the plane of the surrounding wood, 200-300 µm diam, dark brown when dry, appearing paler when wet, smooth, at first closed, opening by a broad circular or elliptical pore to expose the pale hymenium. Peridium uniform, continuous with the basal layer, ca 20 µm thick, composed throughout of interwoven hyphae 1-2 µm diam., tightly packed and not noticeably gelatinous, hyaline below, brown above but not carbonaceous. Epithecium apparently absent. Interascal tissue of narrow pseudoparaphyses 1-1.5 µm in diam., branched, septate, not numerous. Hymenial gel not blueing in iodine. Asci 52-65 x 8-9.5 µm, cylindrical, nearly sessile, not blueing in iodine, thick-walled when young, fissitunicate, the cap about 3 µm thick, without a definite pore, 8-spored. Ascospores biseriately arranged, 14-16.5 x 5.5-6.5 µm, ellipsoidal to slightly ovoid, the apex rounded and the base obtuse, hyaline, 3- (to 5-) septate, constricted at the septa, the second cell from the top usually broadest, fairly thin-walled, smooth, without a gelatinous sheath or appendages.
