Saprobic on dried spine of on Rosa canina. Sexual morph: Undetermined. Asexual morph: Conidiomata 89–240 high × 133–200 μm diam. (x̄ = 155 × 167 μm, n = 6), pycnidial, globose to subglobose, immersed, solitary or confluent. Ostioles apapillate, filled with hyaline cells. Pycnidial wall 11–29 μm (at apex) wide, outermost layer heavily pigmented, thick-walled, comprising reddish-brown to dark brown, flattened cells of textura angularis, inner layer composed hyaline, loosely packed, thin-walled cells of textura angularis.
