Plants epilithic. Rhizome long creeping, sclerenchyma strands absent; rhizome scales basifixed, linear-lanceolate, base auriculate, margin dentate to ciliate, apex acuminate to filiform. Fronds monomorphic, internally dimorphic, stipitate, base without basal fronds or expanded lamina, not articulate; lamina pinnate; pinnae alternate, subtended by distinct raised nectaries; lowermost pinnae rudimentary, sterile pinnae ovate; fertile pinnae linear, apical pinna present; main areoles delimited by veins and connecting veins. Sori acrostichoid, covering abaxial surface except for costa and margins. Sporangia glabrous. Spores with small globules.
One species: China, Indochina, Indonesia, Malaysia, Philippines, Thailand.
Several monotypic genera were segregated from Photinopteris principally by the difference in the form of the fertile pinnae. These were all included within Aglaomorpha by the monographer Roos (Verh. Kon. Ned. Akad. Wetensch., Afd. Natuurk., Sect 2, 85: 227. 1985). Photinopteris is maintained here pending further research, especially molecular evidence.
