Moss

Looking for these colorful mosses. One is used for Pings in England.
Bryum miniatum
Sphagnum rubellum

I've been trying to get some of the Sphagnum rubellum myself. Let me know if you find a source.

I'm not familiar with Bryum miniatum but you can easily grow many Pings in New Zealand LFS and philcula shared his secret source with us a while ago. There's a link somewhere in these threads. Just do a search for New Zealand LFS and it should pop right up.
