whats your favorite emergent moss

[BadgersSong]

Considering adding some unique plants to my paludarium's waterfall areas. Thinking along the lines of liverwort or crystalwort - they seem like great options. I need something that can thrive on a hard surface and grow from a small trickle of water. Java moss is always reliable, but I'm looking for something a bit more exotic. Any personal experiences or recommendations would be appreciated.

Take a walk outside during the cooler months, and observe the mosses thriving in shaded spots.
