Description:Species Description - Rather small epiphytes with erect or short-creeping, often densely clustered rhizomes, these usually immersed in a mass of feltlike roots, and bearing clathrate scales at the apex. Fronds crowded, erect, arching or pendent, the blades simple and entire, narrowly linear, elliptic-linear, or linear-oblanceolate, costate to the apex; veins often obscured by the somewhat opaque tissue, anastomosing to form a single or several rows of areoles between the costa and the inframarginal fertile vein. Sori linear, superficial or immersed in a groove, forming a continuous or subcontinuous inframarginal line; paraphyses present, these usually clavate or capitate, sometimes branched; annulus of 14-18(-20) cells; spores usually ellipsoid and monolete, in a few species tetrahedral-globose and trilete, nearly smooth (very finely papillate under high magnification) but sometimes with scattered granular deposits.
