Notes.

The neotype of this species ( Italy, decaying wood of Prunus domestica, P. A. Saccardo, PAD ; as Ceratostoma notarisii ) was designated by Réblová (2006). The species is characterised by ellipsoidal, slightly apiculate ascospores, sometimes flattened on one side, measuring 6–7 × (3.5 –) 4–5 μm. The ascospores are mid-brown, with a minute pore at each end, and are arranged 1–2 - seriately or in a fascicle within the ascus. Given the shape of the ascospores, the species resembles members of the C. sordida complex, but it clearly differs by having smaller ascospores.
