F. angulifolia is characterised by erect or semi-erect, 2-4-lobed, angular leaves, by mostly incompletely reticulate spores and by rather short elaters  F.  swaziensis can be recognised by large, rounded or sometimes shallowly notched leaves, which are rather stiff and bi- to multistratose basally, by quite large perigonial bracts in the male plants and by spores which have irregular areolae containing tubercular inclusions
