Anamorph: conidiomata several per hymenium, scattered, completely immersed at first, later protruding over the collapsed hymenium, dark brown, somewhat darker than the discoloured hymenial surface of the infested apothecium; 70–100(–130) μm diam., subglobose. Conidiomatal wall dark brown in upper part, pale brown to subhyaline towards the base, 10–15 μm thick, composed of 3–5 layers of flattened cells. Conidiophores absent. Conidiogenous cells 5–6 μm diam., subglobose to broadly obpyriform, proliferating percurrently. Conidia 4.5–6.5 × 2.5–4.5 μm and broadly ellipsoidal or (4–) 5–6 (–7) μm diam. and almost globose, hyaline, quite thick-walled, smooth, without an epispore or gelatinous sheath.
Teleomorph: ascostromata perithecia, in dense groups on the apothecia of the host, almost completely immersed in the discoloured host hymenium; (70–) 100–150 μm diam., ± globose. Ascomatal wall medium to dark brown, 10–15 μm thick, consisting of 3–4 layers of flattened cells. Interascal tissue of pseudoparaphyses, 1–1.5 μm diam. Asci 50–70 × 7–10 μm. Ascospores ± uniseriately or partially biseriately arranged, 12–15 × (4.5–) 5–6 (–6.5) μm, 1-septate, some (less than 5 %) with an additional septum in the upper cell, hardly constricted at the septum, externally protruding torus at the septum indistinct, pale brown, with an inconspicuous verruculose ornamentation, without an epispore or gelati nous sheath.
