White sponge like thing growing on my LR?

I have noticed before a white sponge like thing growing on a couple peices of my LR. But today I found ALOT more on another. I touched it and it was VERY soft. I was a little nervious about touching it due to in the past I touched a bristle worm and that made my finger swell big time. Any of you think you might know what it is? I'm trying to get a neighbor over to take pics of my tank, and all the neat stuff that I have been finding in there. The white bubble type is about a nickle size and is shaped like a dome from the LR. Any ideas? Have any pics of what you might think it is?
