I have a small moss garden. It sorta came with my house, well really it was a patch of my yard that didn't have grass and had some moss instead and I just built a little wall around it and try to keep the leaves off of it. I have also tried to transplant more from around the yard to fill it in more. Anyway I was wondering what they might be. I have googled and found that it is really hard to get a species id, but I would be fine with just a genus, or even a common name. Here are photos of three diffrent ones:
Number 2 reminds me of Buckiella undulata. Number 3 looks like a species of Atrichum to me, but that's only a slightly-informed guess.
