Lindsaeaseae contains genera that were formerly considered part of Dennstaedtiaceae. Molecular data supported the separation of Lindsaeaseae into its own family. Lindsaeaseae is considered the most basal of the order Polypodiales. Characteristics include: Rhizomes short to long creeping; rhizomes with nonclathrate scales or uniserate hairs; blades 1-3 pinnate or more divided; veins usually free; sori marginal or submarginal; indusia open towards margin, sometimes attached at sides, or sori covered by the reflexed segment margin.
The genus Lonchitis has many morphological characteristics similar to Dennstaedtiaceae, but a few characteristics of the spore are similar to the lindsaeoid genera, and molecular data strongly places this genus in Lindsaeaseae
