Stromata 0.5-2 x 0.25-0.5 mm, linear, gray, in clusters and sometimes confluent, deeply immersed and erumpent through the outer layers of host tissue. Stromatal tissue composed of polygonal cells, dark and often occluded in the outer layers. Locules 60-100 (-120) µm diam., ± globose but sometimes slightly elongate parallel with the main axis of the host, in one or more longitudinal rows of 3 to 10, opening through the cracked host tissue. Interascal tissue of rather sparse broad thin-walled pseudoparaphyses, tending to break down at maturity. Asci 46-56 x 6-8 µm, cylindrical, thick-walled and fissitunicate, the apex rounded, with a short tapering stalk, 8-spored. Ascospores arranged uniseriately or obliquely biseriately, 10-11 (-16) x 3 µm, strongly constricted at the ± median septum, the upper cell ± conical and distinctly broader than the lower, ± cylindrical cell, the apex ± acute and the base obtuse, hyaline to pale yellow, smooth, fairly thin-walled, without an epispore or gelatinous sheath.
