I'm trying to grow moss for my paludarium, and there's a certain type of moss that is very common (especially during fall) that you can see growing in hard-packed dirt, trees, and bricks -- (at least where I'm from, Houston, TX, US). It is very common, and looks like:
Is there a certain name for this? I don't think it's java moss or sphagnum, it looks quite different and doesn't get as big. I've tried everywhere and it appears that this is just "moss", but is there at least some type of scientific classification?
After doing some research, I found two possible classifications: Bryophyta oedipodium and Bryophyta bryopsida (true moss). Is it either of these? I am by no means an expert on plant life, I'm doing this for my amphibians, so if anyone is familiar with mosses, any help would be much appreciated!
