'''''Tricholepidium''''' 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== ''Tricholepidium'' was first described by Ren-Chang Ching in 1978.<ref name=CFLW/> A molecular phylogenetic study in 2019 suggested that ''Tricholepidium'' was one of a group of closely related genera in the subfamily Microsoroideae, a group the authors termed "''Lepisorus'' sensu lato". Its species were embedded in a clade in which none of the genera appeared to be monophyletic:<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=== The Pteridophyte Phylogeny Group classification of 2016 (PPG I) separates the monotypic genus ''Lepidomicrosorium'' from ''Tricholepidium''.<ref name=PPGI/> {{As of|2020|February}}, neither the ''Checklist of Ferns and Lycophytes of the World'' nor ''Plants of the World Online'' accepted the separation, and so placed ''Lepidomicrosorium subhastatum'' in ''Tricholepidium'' (as ''Tricholepidium buergerianum'') along with four other species:<ref name=CFLW/><ref name=POWO_17548230-1/> *''Tricholepidium normale'' <small>(Don) Ching</small> *''Tricholepidium subhemionitideum'' <small>(Christ) Fraser-Jenk.</small> *''Tricholepidium superficiale'' <small>(Blume) Fraser-Jenk.</small> *''Tricholepidium venosum'' <small>Ching</small>
