Taken together, classification emphasizing the transitional nature of the hysterothecium, studies in centrum ontogeny and recent molecular evidence, seems to indicate a basal phylogenetic position of the Hysteriales to the Pleosporales and emphasizes the need for further study of the group.

The sole mytilinidiaceous member analyzed in this study, " Lophium mytilinum " ( Pers . ) Fr ., also occupied a basal position to the Pleosporales, but was distant to the core group of Hysteriales and was designated as Pleosporomycetidae " incertae sedis ".

Barr noted ( 1987 ) that the relationship of some members of the Hysteriaceae was with the Cucurbitariaceae or with the Pleosporaceae . but Eriksson ( 2006 ) removed the Mytilinidiaceae from the Hysteriales and considered it as Dothideomycetes et'Chaetothyriomycetes " incertae sedis ", leaving the Hysteriaceae as the sole family in the Hysteriales.

However, it was noted that the hysteriaceous fungi sampled did not form a monophyletic group . " Farlowiella carmichaeliana " ( Berk . ) Sacc . was basal to the Pleosporales, but very distant from the other members of the Hysteriales sampled, which were inclusive of " Hysterium pulicare ", " Hysteropatella clavispora ", and " Hysteropatella elliptica"
