Sphaeria sambuci Pers., Syn. meth. fung. (Göttingen) 1: 14 (1801).

MycoBank number: MB 163394; Index Fungorum number: IF 163394; Facesoffungi number: FoF 00067. Description – see Thambugala et al. (2014a).

Material examined – Austria, Steiermark (Styria) Grazer Bergland, on Sambucus nigra (Adoxaceae), leg D. Baloch 4 October 2002 det. C. Scheuer (GZU 78–2002, epitype).

Notes – As the type specimen is not available, Shoemaker & Hambleton (2005) introduced an epitype specimen for D. sambuci from Sambucus nigra (Adoxaceae) in Austria. There is no identified asexual morph for D. sambuci. According to phylogenetic analysis by Thambugala et al. (2014a), D. sambuci groups with D. insculpta and this was confirmed in our study.
