Saccoloma is a small pantropical genus of about 12 species, mostly of the southwestern Pacific, with only four species in America, which occur at low to middle elevations in wet forests. It is distinct in its generally large, coriaceous fronds, rhizome indument of scales, submarginal, dis-
crete or subdiscrete sori, and spores with parallel ridges.
