In 2011, Quaedvlieg et al. introduced a new combination for this species: Zymoseptoria tritici (Desm.) Quaedvlieg & Crous, 2011, as they found that the type strains of both the genus "Mycosphaerella" (linked to the anamorph genus "Ramularia") and the genus "Septoria" (linked to the genus "Septoria", an extensive clade of very distinct septoria-like species within the "Mycosphaerellaceae") clustered separately from the clade containing both "Zymoseptoria tritici" and "Z. passarini". Since 2011, a total of seven "Zymoseptoria" species have been described within the genus "Zymoseptoria"; "Z. tritici" (the type of the genus "Zymoseptoria"), "Z. Pseudotritici, Z. ardabilia, Z. brevis, Z. passarini, Z. halophila" and "Z. verkleyi" (Named after Gerard J.M. Verkleij, for the contribution that he has made to further the understanding of the genus "Septoria").
