Identification. Leaves patent to suberect leaves, with slightly arched, entire, slightly crenulate anterior margins, and straight, crenulate posterior margins; apexes rounded to acute. This species can be confused with Lejeunea phyllobola Nees & Mont. , but the smaller size of the gametophyte and the finely papillose cuticle in L. oligoclada distinguishes these two species. Briocenological group: saxicolous.
