Rhizome 1-1.5 mm in diam.; scales light brown, 3-6 × 1-1.2 mm. Lamina linear, 30-60 × 0.2-0.5 cm. Sori 1.5-2 mm in diam.; paraphyses 0.15-0.3 mm in diam.

Lepisorus loriformis and L. steniste differ only in lamina width, the former with laminae 0.5-2.5 cm wide and the latter not more than 0.5 cm. These two species are sympatric, and the former usually occur at higher elevations, so species rank has not been accepted. This is not accepted by Li Wang et al. (Molec. Phylogen. Evol. 54: 221. 2010) whose molecular analysis placed the two taxa within different well-supported subclades.
