Description:
Species Description - Rhizomes short-creeping, 1–2 mm diam.; rhizome scales linear, with sparse and irregular short teeth, brown to dull orange, 3–5 mm long; fronds clumped, 8–18 x 0.8–1.5 cm; phyllopodia absent; stipes slender, 1/5–2/5 the frond length, moderately clothed with slender, dull orange, subulate, spreading scales 2–3 mm long; blades narrowly elliptic, bases cuneate, apices gradually acuminate, lamina thin; veins conspicuous, free, mostly simple or rarely once-forked, 1.5–2 mm apart, at ca. 40º angle to costa; hydathodes conspicuous; blade scales subulate, dull orange, moderately and uniformly clothing blade surfaces, more so on abaxial surfaces, longer and spreading at blade margins; fertile fronds nearly as long as the sterile but more elliptic, ca. 3 cm long and 1.1 cm wide, with acute apices and longer stipes ca. 3/4 the frond length, intersporangial scales abundant.

This species is superficially much like E. crinipes, but it can be distinguished by the smaller frond size and the presence of scales among the sporangia. It is also like E. monicae, which has more elliptic blades and darker blade scales.
