Myriopteris aurea is rare in the Gila National Forest where it is at the most northern extent of its range, but it is the most abundant fern in west central Mexico. It easily mistaken for Astrolepis windhamii with which it is found growing together on rocky slopes. However, the abaxial surface of Astrolepis windhamii is covered in brown scales, while that of Myriopteris aurea is covered in dense white hairs. Also, the pinnae of Myriopteris aurea appear to have a short petiole, though technically the pinna is simply articulate.
