Description: Spores bean-shaped, yellow, 40–45 × 15–18 μm, smooth, covered with perisporium forming curving and twisting subhyaline ridges and sacci (winglike compressed inflated folds). Most African taxa, such as Dryopteris kilemensis (Kuhn) Kuntze, Dryopteris inaequalis (Schltdl.) Kuntze and Dryopteris pentheri (Krasser) C. Chr., have a smooth perine surface and typically inflated sacci with superficial ridges (Tryon and Lugardon, 1990).

(Sub-) Fossil occurence: No information

Co-occurence: No information

Modern occurence: Dryopteris is distributed nearly worldwide in both temperate and tropical regions. Dryopteris species are mainly found in shaded habitat along forest margins and streams in evergreen forest (Burrows, 1990).
