I have a greenish mushroom (maybe a yuma) and a green ric that a WCR member can have. They have some algae on the rock around the base, but it should be easy to clean off. I'm heading out to CRE this Saturday, and could arrange to meet someone if there is any interest. Otherwise, I am in Windsor.
I also have GSP and red mushroom rocks, but they are rather algae infested, so take at your own risk.
