Ascomata immersed beneath raised surface under several layers of tissue which are not discoloured, 180-300 μm high × 300-600 μm diam, globose to ellipsoidal, dark brown, solitary or in small clusters. Neck comprised of several layers of compressed cells, long cylindrical, 400-800 μm long × 120-180 μm diam, yellow to light orange. Peridium pale brown, comprised of 2-3 strata, inner layer comprising of compressed angular cells, outer layer cell less distinct and fusing with host at the outside, 6.9-25.3 × 2.3-5.7 μm ( = 14.3 × 4.3 μm, n = 20). Paraphyses up to 6 μm wide at the base, rounded at the base and acute at the apex, numerous, filamentous, septate, unbranched, hyaline, tapering, longer than asci. Asci 135-170 × 5-8.5 μm ( = 147 × 6.8 μm, n = 30), 8-spored, cylindrical, apedicellate, apex rounded to slightly acute, with a J-, cylindrical apical ring, 2-5 μm high × 2-3 μm diam. Ascospores 85-137 × 2.5-3 μm ( = 120 × 2.5 μm, n = 30), filiform, 4-7-septate, hyaline (in mass, yellow to light orange), slightly acute at the apex and rounded at base, without sheaths or appendages.
