Description: Spores bean-shaped, yellow to brown, 42–55 × 28–38 μm, smooth, covered with perisporium developed into fairly high and coarse, subhyaline ridges. These ridges anastomose or not, bear small echinae (spines) on top and columella-like structures underneath.

Modern occurence: Asplenium is one of the largest fern genera, distributed worldwide from Greenland and Europe to South America and New Zealand (Tryon and Lugardon, 1990). It occurs in a wide variety of exposed or partly shaded habitats, e.g., on rocks, in low-altitude semi-deciduous woodland, wet evergreen forest and (sub)montane rain forest (Burrows, 1990; Hemp, 2002).
