Type species: Pseudoseptoria donacicola Speg., Anal. Mus. nac. B. Aires, Ser. 3 13: 388 (1911), Facesoffungi number: FoF00135

Notes: Pseudoseptoria was introduced by Spegazzini (1910) as an asexual genus in order to accommodate Pseudoseptoria donacicola (P. donacis). This genus is characterized by immersed, branched, septate, pale brown mycelium, pycnidial, solitary or linearly aggregated, immersed, brown, globose, unilocular, thin-walled conidiomata of pale brown cells of textura angularis with a distinct, central, circular ostiole. Conidiogenous cells are discrete, determinate or indeterminate, hyaline, smooth, ampulliform with a prominent cylindrical papilla and falcate. Conidia are fusoid, hyaline, aseptate, guttulate, smooth, thin-walled, and acutely rounded at each end (Sutton 1980; Quaedvlieg et al. 2013). Wijayawardene et al. (2012) placed this genus in Ascomycota, genera incertae sedis. Quaedvlieg et al. (2013) introduced two new species, P. collariana and P. obscura and placed them in Dothioraceae, based on molecular phylogeny and stated that P. donacis (CBS 291.69, 313.68 and 417.51), the type species of Pseudoseptoria formed a monophyletic lineage with P. collariana and P. obscura. In this study P. collariana and P. obscura clustered in Aureobasidiaceae as a sister clade to Selenophoma linicola (CBS 468.48). Considering these facts we accept Pseudoseptoria in Aureobasidiaceae as a distinct genus.
