Genera
Athyriaceae contain the following five genera.
Athyriaceae have, in the past, included Cystopteris and Gymnocarpium, now part of Cystopteridaceae. Inversely, this family has by some been subsumed in the family Woodsiaceae, but a Woodsiaceae defined in this way may be paraphyletic if it omits the Onocleaceae and Blechnaceae (as of 2006, the evidence was not clear).
Phylogenic relationships
The following diagram for the eupolypods II, based on Lehtonen, 2011, and Rothfels & al., 2012, shows a likely phylogenic relationship between Athyriaceae and other families of the eupolypods II clade.
This phylogenic diagram shows a possible relationship between the genera of the Athyriaceae.
