Lepidomicrosorium is a genus of ferns in the family Polypodiaceae, subfamily Microsoroideae, with a single species, Lepidomicrosorium subhastatum, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I).[1] Other sources do not accept the genus, submerging it into Tricholepidium, with Lepidomicrosorium subhastatum becoming Tricholepidium buergerianum (Miq.) Fraser-Jenk.[2][3]
Phylogeny
A molecular phylogenetic study in 2019 suggested that Lepidomicrosorium was one of a group of closely related genera in the subfamily Microsoroideae, a group the authors termed "Lepisorussensu lato". Its sole species was embedded in a clade in which none of the genera appeared to be monophyletic:[4]
