Didymochlaenaceae was recently described by Zhang & Zhang (2015, Taxon 64: 27–38) to accommodate this unique species. The family is sister to the rest of the eupolypods I and can be readily recognized by 2-pinnate leaves, dimidiate pinnules, elongated sori, and a cluster of short emergences at the junctures of axes adaxially. Furthermore, it has reddish brown young leaves, which inspired its common name in horticulture: mahogany fern.
