Recent studies agree that the prasinophytes are not a natural group, being highly paraphyletic. Relationships among the groups making up the Chlorophyta are not fully resolved. The cladogram produced by Leliaert et al. 2011 and some modification according to Silar 2016, Leliaert 2016 and Lopes dos Santos et al. 2017 is shown below. The blue shaded groups are or have traditionally been placed in the Prasinophyceae). The species "Mesostigma viride" has been shown to be a member of the Streptophyta or basal Green algae.
