Anyone ID this little guy coming to life under a red mushroom frag?

Mushroom itself is about half the size of a dime, for now (haha) if that helps.

Looks like a different mushroom if some sort?

The linearity of the polyps is interesting. I'm thinking of letting it get bigger to see what becomes of it. Hopefully it doesn't get buried by the red mushroom. Might have to move it soon.
