Terrestrial ferns. Rhizomes short- to long-creeping, scaly. Rhizome scales non-clathrate, narrowly ovate or trichome-like. Fronds monomorphic. Stipes pale brown, glabrous. Laminae 2–4-pinnate, herbaceous or coriaceous, glabrous. Veins free. Sori oblong or slightly extended laterally, superficial, marginal or submarginal; paraphyses present. Indusia always present, attached at base and sides, opening towards the margin. Spores monolete or trilete, perispores smooth or granulate.
As circumscribed by Lehtonen et al. (2010), Odontosoria includes many species that were previously treated in Sphenomeris. It remains poorly defined morphologically, albeit genetically distinct from the other genera of Lindsaeaceae.
A pantropical genus of more than 20 species (Kramer 1990; Lehtonen et al. 2010), with 12 in the Neotropics and the remainder in the Old World tropics and Pacific islands. Absent from Australia (Kramer 1990). One species casual in New Zealand.
