This little moss is positively overflowing with asexual propagules called gemmae. If you zoom in on the photo you should be able to see them - they are bright yellow green rounded packets of cells nestled into and falling out of the leaf axils. This is on flat disturbed soil at the base of bush mallow along with many other species of mosses.

The photo taken under the microscope shows one leaf and one gemma. The gemma has little leaf like projections (primordia) and there are many gemmae per leaf axil which indicates G. barnesii
