Weird appendage coming off of my mushroom.

[Arthurd216]

Hi guys have a BioCube 16 reef tank. Couple of fish soft corals mushrooms and inverts. I was just up at blue fish aquariums in Mayfield heights Ohio last week. They had just broken down a big tank and had a bunch of discount mushrooms that I just couldn't resist. So when I got them all home one of them unrolled and was about 3in diameter and now appears to have what I can only describe as a siphon similar to what comes off of a snail?? I have never encountered this before and wanted to see if you guys could help me identify. Best I can tell it is attached to the the mushroom but it certainly is possible that is it a separate organism. any help would be greatly appreciated I want to make sure I'm caring for this thing properly.
Lol maybe this one's just well endowed.

It may actually just be under the mushroom. My guess is that its some kind of tunicate.

Welcome to R2R!!! Tunicate or sponge.

Thanks for the warm welcome! I have to put an update on this because its appearance seems to have changed and now it looks like some sort of polyp.
