Hysterothecia isolated or gregarious, erumpent to entirely superficial, navicular to linear to highly flexuous, even triradiate, often striated on the outer margin, sometimes arranged in parallel orientation and confluent linearly to some degree, but never dichotomously branched and never associated with a subiculum or stroma. In vertical section, hysterothecia are globose to obovoid, typically with a thick three-layered peridium, composed of small pseudoparenchymatous cells, the outer layer carbonaceous, the middle layer lighter in pigmentation and the inner layer distinctly thin-walled, pallid and compressed. Hysterothecium stout, much stronger than that found in the Gloniaceae. Pseudoparaphyses cellular, persistent, branched and united above forming the epithecium. Asci cylindric, clavate, and octosporous. Ascospores uniseptate, hyaline to pale yellow in mass, obliquely uniseriate or sub-biseriate, oblong or ovoid, the lower cell often narrower and constricted at the septum, usually with at least the apex of the upper larger cell broadly rounded, although there are instances where both ends of the ascospore may be acuminate, as in the genus Glonium.
