Discussion:

Molendoa is a genus of small, yellow-green to glaucous-green mosses having a stem central strand, lateral perichaetial, and a costa in cross-section with two stereid bands as well as a ventral epidermal layer of enlarged, smooth cells. Many of these features, however, are variable and sometimes difficult to demonstrate. The genus is similar to Anoectangium, and when considered on a world-wide basis the two genera are especially difficult to separate (see Zander 1993). In Central America Anoectangium can be distinguished from Molendoa by its more acute, strongly keeled leaves that have a single (dorsal) stereid band in the costa. Zander (1977) provided an in-depth treatment of the genus in Middle America.
