Unknown moss from Kuching, Malaysia

Photo taken by the stereomicroscope.

No sporangium is found, so the identification may be impossible. It seems that this moss can grow underwater, so I consider it as an aquatic species.

Leaves grow from the abaxial surface.

Rhizoids are aligned with the stereid band.

These mosses grow on the leaves of Rhaphidophors beccarii, but it isn't hard to separate them apart.
