I'm no expert in moss, I just took similar looking pieces from various pots and grouped them together. I doubt I can actually get any accurate species identification from any of these without getting a professional to look at the spores or something, but they look similar to:
Orangish ones: Sphagnum fuscum
Redgreen ones: Sphagnum russowii
Red ones: Sphagnum rubellum
For the green ones I see species with very thick spongy leaf parts and a species with thinner ones and smaller heads.
Anyone else have a bunch of interesting sphagnum?
And here's a pot of mostly red sphagnum that some of my helis live in:
I periodically mow the top part of these pots and spread them around my other pots. I think I have way more red ones than any other color at the moment.
