Thank you very much for sharing your work. I looked at the methods and results and I have a few concerns regarding the validity of species identification.

Only the genealogy of the concatenated dataset is shown. The 10 individual gene trees are not presented, so I cannot get an idea of the level of discordance across genealogies. What would be the result of Genealogical Concordance Phylogenetic Species Recognition ( Table 3 suggests that most of the divergence in the total evidence genealogy is caused by one gene (MPG1). Table 4 shows that there is also exclusive polymorphism at one gene in one of the wheat-infecting lineages. Is it sufficient to conclude that these lineages are reproductively isolated and form distinct phylogenetic species?
