dear collegues It thus seems that the the clade (Polypodium + Myxozoa) is not closely related to the Hydrozoa and it probably constitutes a new class within the Cnidaria. The autapomorphy for this clade would be endocytic parasitisms (+support from 18S RNA sequence analysis). A new name for this clade could be: Endocnidozoa.

If there is no evidence supporting (Polypodium + Myxozoa) within a hypothetically monophyletic Hydrozoa, then these taxa should not be placed there in a phylogenetic classification. However, the tendency to proliferate higher category names should be avoided. There's nothing wrong with "classifying" these taxa as Cnidaria incertae sedis until further analysis provides evidence for which of the monophyletic cnidarian lineages contains (or is) the sister group.
