Antrophyum Kaulf.

Plants epiphytic or epilithic, small to medium-sized. Rhizome short erect or creeping, densely covered with clathrate, iridescent scales, and roots with numerous water-absorbing root hairs. Fronds simple; lamina fleshy, or leathery, shrunken when dry, broadly lanceolate or oblanceolate, sometimes linear, spatulate, obovate, or suborbicular, rarely forked at apex, mostly gradually narrowed into a stipelike base; costa usually only present in basal part; lateral veins abundantly reticulate, without free included veinlets. Sori forming coenosorus, soral lines superficial or immersed, on lateral veins, netted or branched, less often simple; paraphyses abundant, club-shaped with a capitate head, or taeniform, or filiform. Spores trilete, tetrahedral-globose, surface low-papillate, often with scattered spherules and rodlets.

They commonly grow in moist but airy situations, especially in rainforest and cloud forest.
