According to Eddy (1996) and Vitt et al. (1995), this species is characterized by having smooth and flat lamina cells throughout the leaf, ovoid capsules borne on a long seta reaching often to 1. 5 cm, and a naked, plicate calyptra.

Macromitrium microstomum View in CoL , had been known earlier from the Philippines by its synonym, M. reinwardtii View in CoL , and had already been reported from Luzon, Mindoro, and some islands in the Visayan Region ( Tan and Iwatsuki, 1991); we now add Mindanao to the list. Otherwise, Macromitrium microstomum View in CoL is widespread throughout tropical SE Asia reaching Australia, New Zealand, and Oceania.
