Pseudoalternaria was described with the type species Pseudoalternaria arrhenatheria, and Alternaria rosae was transferred to Pseudoalternaria based on morphological and molecular data (single and combined ITS/gpd/Plasma membrane ATPase) (Lawrence et al. 2014). The morphology of Pseudoalternaria is similar to Alternaria, but phylogenetic analysis, showed that Pseudoalternaria formed an independent lineage basal to Alternaria. Lawrence et al. (2016) transferred Pseudoalternaria to a new section of Alternaria (sect. Pseudoalternaria). However, Pseudoalternaria is invalid (Art. F.5.1, Shenzhen).
Type species: Pseudoalternaria arrhenatheri D.P. Lawr., Gannibal, F.M. Dugan & B.M. Pryor
Other described species:
Pseudoalternaria rosae (E.G. Simmons & C.F. Hill) D.P. Lawr., Gannibal, Dugan & B.M. Pryor
