(2006), using a multigene phylogeny of the Dothideomycetes, based on nu SSU, nu LSU, EF1a & RPB2, provided evidence indicating that hysteriaceous fungi occupy a basal position to a monophyletic Pleosporales, in agreement with Luttrell (1955).However, it was noted that the hysteriaceous fungi sampled did not form a monophyletic group.
