'''''Lemmaphyllum''''' is a genus of [fern](/source/fern)s in the family [Polypodiaceae](/source/Polypodiaceae), subfamily [Microsoroideae](/source/Microsoroideae), according to the [Pteridophyte Phylogeny Group](/source/Pteridophyte_Phylogeny_Group) classification of 2016 (PPG&nbsp;I).<ref name=PPGI/>

==Taxonomy==
''Lemmaphyllum'' was first described by [Carl Presl](/source/Carl_Borivoj_Presl) in 1851.<ref name=CFLW/> A [molecular phylogenetic](/source/Molecular_phylogenetics) 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](/source/Sensu)".<ref name=TestFielSessSund19/>
