Microsoroideae is a subfamily in the fern family Polypodiaceae in the Pteridophyte Phylogeny Group classification of 2016 (PPG I).
[1] The subfamily is also treated as the tribe Microsoreae within a very broadly defined family Polypodiaceae sensu lato.
[2] In either treatment, it includes the previously separated tribe Lepisoreae.
The Pteridophyte Phylogeny Group classification of 2016 (PPG I) recognized the following genera, while accepting that some needed further evaluation:[1] A molecular phylogenetic study in 2019 suggested the following relationship between the PPG I genera (Thylacopteris was not included in the study):[3] Lemmaphyllum Lepidomicrosorium + Neocheiropteris + Neolepisorus + Tricholepidium Lepisorus s.s. Paragramma (as Lepisorus longifolius) Microsorum Leptochilus Bosmania Dendroconche Zealandia Lecanopteris Goniophlebium Species placed in the PPG I genera Lepidomicrosorium, Neocheiropteris, Neolepisorus and Tricholepidium were intermingled in a single clade.
are treated differently by PPG I, the Checklist of Ferns and Lycophytes of the World (CFLW) and Plants of the World Online (PoWO), as shown in the following tables.
