Notes.

The monotypic genus Acicuseptoria was described by Quaedvlieg et al. (2013) as a segregate of the polyphyletic genus Septoria , and it was characterised by brown, globose pycnidia with conidiophores reduced to ampulliform conidiogenous cells bearing acicular, hyaline, euseptate conidia. However, its position within the Leptosphaeriaceae remained undetermined as no other representatives of the family were included in their phylogenetic tree ( Quaedvlieg et al. 2013: fig. 2). In our phylogenetic analyses (Fig. 2 ), Acicuseptoria rumicis is embedded within the genus Paraleptosphaeria and placed in a highly supported subclade that also contains the generic type, P. nitschkei . Acicuseptoria rumicis is therefore transferred to the genus Paraleptosphaeria .
