I found a strange looking growth on one of my rocks after transferring it from one tank to another. I have a picture but I don't know how to post it. I'm going to try and insert it but, in case it doesn't show, I'll describe it. It is a small circular growth that is light purple in color and feels spongey. It is about the size of a quarter and is on one of the first LR's I bought a year ago. There is a smaller piece close by that is roughly 1/4 round. I have only one type of shroom in the tank right now and it is red. Thanks for the help. Sorry if the picture doesn't load.
