Nephrolepis dicksonioides has been confused with N. abrupta and N. acuminata. It has fertile pinnae similarly incised as typical specimens of N. acuminata, and marginal sori similar to those of N. abrupta, but differs from both in the indusium having a broad base, innervated by 2 or 3 veins. The apex of the sorus-bearing tooth is often dilated. From N. abrupta it can also be distinguished by the shape of the pinnae: the fertile ones are more constantly deeply divided, the sterile ones more distinctly acuminate, narrowing to a distinct cauda from c. halfway.
