'''''Lemmaphyllum''''' is a genus of ferns in the family Polypodiaceae, subfamily Microsoroideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I).<ref name=PPGI/>
==Taxonomy== ''Lemmaphyllum'' was first described by Carl Presl in 1851.<ref name=CFLW/> A molecular phylogenetic study in 2019 suggested that ''Lemmaphyllum'' was one of a group of closely related genera in the subfamily Microsoroideae; a group the authors termed "''Lepisorus'' sensu lato".<ref name=TestFielSessSund19/> {{clade |label1=''Lepisorus'' s.l. |1={{clade |1={{clade |1=''Lemmaphyllum'' |2=''Lepidomicrosorium'' + ''Neocheiropteris'' + ''Neolepisorus'' + ''Tricholepidium'' }} |2={{clade |1=''Lepisorus'' s.s. |2=''Paragramma'' (as ''Lepisorus longifolius'') }} }} }}
===Species=== {{As of|2020|February}}, the ''Checklist of Ferns and Lycophytes of the World'' recognized the following species:<ref name=CFLW/> *''Lemmaphyllum carnosum'' <small>(Wall. ex J.Sm.) C.Presl</small> *''Lemmaphyllum diversum'' <small>(Rosenst.) Tagawa</small> *''Lemmaphyllum drymoglossoides'' <small>(Baker) Ching</small> *''Lemmaphyllum microphyllum'' <small>C.Presl</small> *''Lemmaphyllum rostratum'' <small>(Bedd.) Tagawa</small> *''Lemmaphyllum squamatum'' <small>(A.R.Sm. & X.C.Zhang) Li Wang</small>
''Plants of the World Online'' also accepted ''Lemmaphyllum accedens'' <small>(Blume) Donk</small>, which the ''Checklist of Ferns and Lycophytes of the World'' placed in ''Lepisorus''.<ref name=POWO_17336440-1/>
