Phegopteris is a genus of ferns in the family Thelypteridaceae, subfamily Phegopteridoideae, in the Pteridophyte Phylogeny Group classification of 2016. They are known collectively as the beech ferns. Species are native to Asia, North America and Europe.
Microsorum is a genus of ferns in the family Polypodiaceae, subfamily Microsoroideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). The species are tropical. Like most ferns, they grow from rhizomes, rather than roots. The genus name is often misspelled "Microsorium" or "Microsoreum". It includes some species that are lithophytic rheophytes.
Aleuritopteris is a genus of ferns in the Cheilanthoideae subfamily of the Pteridaceae. As with some other genera of the Cheilanthoideae, molecular phylogenetic studies have suggested that it is not monophyletic, and so may need to be circumscribed differently in future.
Arachniodes is a fern genus in the family Dryopteridaceae, subfamily Dryopteridoideae, in the Pteridophyte Phylogeny Group classification of 2016. A number of species in this genus are known as "holly ferns".
Bolbitis is a genus of ferns in the family Dryopteridaceae, subfamily Elaphoglossoideae, in the Pteridophyte Phylogeny Group classification of 2016.
Leptochilus is a fern genus in the family Polypodiaceae, subfamily Microsoroideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I).
Neocheiropteris is a genus of ferns in the family Polypodiaceae, subfamily Microsoroideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I).
Tectaria is a genus of fern in the family Tectariaceae, according to the Pteridophyte Phylogeny Group classification of 2016. Halberd fern is a common name for species in this genus.
Trichomanes is a genus of ferns in the family Hymenophyllaceae, termed bristle ferns. The circumscription of the genus is disputed. All ferns in the genus are filmy ferns, with leaf tissue typically 2 cells thick. This thinness generally necessitates a permanently humid habitat, and makes the fronds somewhat translucent. Because of this membrane-like frond tissue, the plant is prone to drying out. “Filmy ferns” in the taxa Hymenophyllaceae grow in constantly wet environments. Many are found in cloud forests such as “Choco” in Columbia. There are also members of the taxa that can grow submersed in water.
Enterosora is a genus of ferns in the family Polypodiaceae, subfamily Grammitidoideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). PPG I also recognizes the genus Zygophlebia, which more recent sources include in Enterosora. As of February 2019, many do not have formally published names in Enterosora and are retained here in Zygophlebia.
Deparia is a genus of ferns. The Pteridophyte Phylogeny Group classification of 2016 places the genus in the family Athyriaceae, although other sources include it within an expanded Aspleniaceae or Woodsiaceae.
Christella is a genus of around 70-80 species of ferns in the subfamily Thelypteridoideae of the family Thelypteridaceae in the Pteridophyte Phylogeny Group classification of 2016. Other sources sink Christella into a very broadly defined genus Thelypteris. The genus was named after Konrad H. Christ, a Swiss botanist. The distribution of these plants is mostly in the tropics and sub tropical areas. An Australian example is C. dentata.
Vandenboschia is a fern genus in the family Hymenophyllaceae. The genus is accepted in the Pteridophyte Phylogeny Group classification of 2016 but not by some other sources.
Abrodictyum is a fern genus in the family Hymenophyllaceae. The genus is accepted in the Pteridophyte Phylogeny Group classification of 2016 but not by some other sources, which sink it into a broadly defined Trichomanes.
Austroblechnum is a genus of ferns in the family Blechnaceae, subfamily Blechnoideae, according to the Pteridophyte Phylogeny Group classification of 2016. The genus is accepted in a 2016 classification of the family Blechnaceae, but other sources sink it into a very broadly defined Blechnum, equivalent to the whole of the PPG I subfamily.
Mildella is a genus of ferns in the subfamily Cheilanthoideae of the family Pteridaceae. Species are native to Mexico, Central America and the Caribbean.
Stegnogramma is a genus of ferns in the subfamily Thelypteridoideae of the family Thelypteridaceae in the Pteridophyte Phylogeny Group classification of 2016. Other sources sink Stegnogramma into a very broadly defined genus Thelypteris.
Goniopteris is a genus of ferns in the family Thelypteridaceae, subfamily Thelypteridoideae, in the Pteridophyte Phylogeny Group classification of 2016. Other sources sink Goniopteris into a very broadly defined genus Thelypteris.
Parapolystichum is a genus of ferns in the family Dryopteridaceae, subfamily Elaphoglossoideae, in the Pteridophyte Phylogeny Group classification of 2016. The genus is mainly native to the tropics, although its range extends to southeastern Australia.
Lepisorus is a genus of ferns in the family Polypodiaceae, subfamily Microsoroideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I).
