Kirschstein, Krypt.-Fl. Brandenburg 7: 249. 1911. = Ceratostoma notarisii Sacc., Nuovo Giorn. Bot. Ital. 7: 308. 1875. Description. See Réblová (2006). Specimens examined. France • Pyrénés Atlantiques, Ariège, Rimont, Las Muros; on decaying wood of Prunus domestica; 3 Feb 2002; J. Fournier J. F. 02022 (PRA -21826) • Ibid.; 21 Apr 2002; J. Fournier J. F. 02070 (PRA -21827). Habitat and geographical distribution. Saprobe on decaying wood of Betula papyrifera, Prunus domestica, and on decaying basidioma of Fomes fomentarius, known in Canada, France, Italy, and Poland (De Notaris 1867; Réblová 2006; MyCoPortal). 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.
