A friend sent me this link to a bath mat made of moss. They don't specify what types of mosses they are using, but it looks to be Hypnum or maybe Thuidium. It would make for a pretty interesting bathroom experiment. Mosses do not require too much light and they love high humidity levels, thus the bathroom sounds like the perfect place.
I do wonder where they are getting the mosses. Wild collected, from a local landscaper, or are they growing them for this particular project?
