The sporocarps are firm, and compressed-ovate to globose. They may be slender-pedunculate or subsessile. They lack an annulus. They are trilete. Microspores are minute, and borne in groups of 16-64 within microsporangia .
Megaspores are larger, and solitary within each megasporangium .
Slender and often branched, they are hardly indurate but bear trichomes. Circinate in bud, they are filiform, or have a long petiole with 2 or 4 leaflets. They range from 1-40 cm in length.
