I collected the mushrooms from a tree in my back yard and they are already dried out As far as the moss goes I bought zoo med terrarium moss(sphagnum moss) will that moss start growing? I didn't think it would. I knew frog moss would but not that one. paper clipping it is a great idea for most of what I am doing however I am covering one side of my water feature tube to hide it. would silicone be the best for doing that?
