See text Lellingeria is a genus of ferns in the family Polypodiaceae, subfamily Grammitidoideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I).

Rhizome radially symmetrical or dorsiventral, with clathrate, usually blackish scales that are attached across their entire base.

[3] At that time, it consisted of 52 species, three newly described, and 49 transferred from the artificial (unnatural) genus Grammitis.

In 2004, a phylogenetic study of DNA sequences of two chloroplast genes showed that Lellingeria, as defined in 1991, was polyphyletic.

Lellingeria can be distinguished from Melpomene by the lack of setae, the presence of hairs on the rhizome, the sparse covering of very short hair on the upper surface of the rachis or midrib, and by the sori, which are slightly sunken into the lamina.
