Saprobic on Clematis vitalba L. in terrestrial habitats. Sexual morph: Ascomata 170–182 μm high × 137–168 μm diam. (x̄ = 174 × 149 μm, n = 5), superficial, solitary or scattered on the host surface, globose to subglobose, with flattened base, ostiole in the center, not easy to remove, black, without papilla. Peridium 14–20 μm wide, composed of several layers of brown to dark brown, flattened pseudoparenchymatous cells, arranged in a textura angularis. Hamathecium of 1.3–1.7 μm wide, long cylindrical, cellular, anastomosed, septate, pseudoparaphyses.

or sessile. Ascospores 21–30 × 5–8 μm (x̄ = 26 × 6 μm, n = 20), overlapping 2–3-seriate, hyaline, fusiform, straight or slightly curved, 1-septate in center, slightly constricted at the median septa, swollen with large guttules in each cell, lacking a mucilaginous sheath, smooth-walled.
