Notes
Possible confusion with A. onopteris L., 1753, which has larger fronds (20-40 cm), usually caudate pinnae, and mucronate pinnule teeth, while A. adiantum-nigrum has smaller fronds (10-30 cm), non-caudate pinnae, and non-mucronate pinnule teeth.
The differentiation between A. onopteris and large individuals of A. adiantum-nigrum can be complicated, if not impossible, in the field. In this case, measuring the size of the spores remains the only reliable solution to differentiate the two species.
The following infraspecific taxa are accepted:
- A. adiantum-nigrum subsp. adiantum-nigrum: allotetraploid (2n = 144)
- var. adiantum-nigrum L., 1753, P;
