Members of the family all have intramarginal, linear sori with a flap-like indusium arising along one edge. Most workers today consider this family of solely consisting of the genus Asplenium. Others still maintain segregate genera such as Camptosorus, Phyllitis, and Ceterach; however, the species segregated into these genera all hybridize readily with undisputed Asplenium species.

The scales consist of cells with dark, thick, radial walls and clear, thin, tangential walls, giving the scales a clathrate (latticelike) appearance reminiscent of lead moldings between plates of stained glass.
As construed here, Aspleniaceae comprise a single, huge, extremely diverse genus, Asplenium.
A satisfactory taxonomic division into subgenera or satellite genera has not been possible because of the absence of any significant gaps.
