Where did you get the "wood?" Is is really corkbark or is it something like grape wood that you're using? Corkbark should not do this---lichen would be on the top of the bark (the exterior), not under it.
If you're using grape wood, it's not meant to be kept submerged in water, and the part that is will develop a whitish/pale green slime on it that will grow (I can imagine it looking like moss) and the wood will eventually rot. How long has the wood been in the water? I don't think it would be harmful to your turtle.
I had what I described above when I tried grape wood, and my turtles would eat it (it didn't hurt them). I would have to take the wood out and clean it frequently which was a pain, so I stopped using it.
What kind of "wood" are you using?
