Descripción
Rhizomes ca. 0.5–1 mm diam.; rhizome scales ferrugineous to stramineous, mostly 2–4 mm long, linear-lanceolate with longattenuate apices, entire, ± appressed but with spreading tips; fronds strongly dimorphic; stipes 0–4 mm long in sterile fronds, 0–10 mm in fertile fronds; sterile blades nearly exstipitate, elliptic to ovate, to ca. 6 X 1 cm, acute to cuneate at bases, acute to rounded at apices; fertile blades linear, ca. 5(–9) cm X 2–3(–4.5) mm; indument of scattered, ferrugineous, peltate-based scales on both sides of blades, scales with pale, fringed margins and a tail often longer than body of a scale; sori when mature usually projecting beyond margins of fertile blades, with numerous, tan acicular scales among the sporangia.

Discusión taxonómica
Microgramma reptans is most closely related to M. piloselloides and M. tecta, which see. From the former it differs by its lanceolate to ovate sterile blades and slightly thicker rhizomes with more appressed scales; from the latter it differs chiefly by the narrower fertile blades with mature sori projecting beyond the blade margins.A
