I've been meaning to photograph and also to ask, but can you tell me a little about the greenish off white fungus stuff growing at Sever Lake. It appears to be softball size/shape and larger and grows on some submerged trees. Its not on all trees, and cant say that fish avoid or congregate near them. Oddly, I also can't say I've seen it in other lakes and don't recall it in farm ponds. Any idea what makes it seem to be isolated to that lake. It only appears to grow within a foot or so of the surface. I've never seen it deeper really, and sometimes that lake gets clear. Now I'm thinking there might be a little at Fox Valley Lake.
