I was poking around in one of my plant pots when I noticed a bunch of green star shaped moss things growing. They aren't flat against the ground, they stand up a little bit. I picked them out because they keep popping up in that pot. Also, in my D. Capensis pot, there's this thing that looks similar to that other moss but is bigger, and is a brighter green-yellow color. The tips of it is brown, and it grows very slow, much slower than the other moss. Are either of these things sphagnum?
