Rhizome creeping, covered with scales at least when young, but in some species the scales are fugacious; scales clathrate, brown to black, peltate near base. Stipes articulate;laminae pinnate or deeply pinnatifid, venation usually reticulate, forming at least one row of costal areolae with included forked veinlets, sometimes free and forked. Sori round, usually in one row on either side of costa, borne in the areolae at end of included veinlet, or on the acroscopic branch of a free forking vein.
