Help identifying white tissue on mushroom coral

[DBUM]

I have an interstellar mushroom frag and I'm beginning to get some white tissue on the mushroom. It's in an area of moderate light and flow so any ideas would help. I did notice some type of critter on the coral but it looks nothing similar to the common pests I've heard about. Let me know what I should do for both here are some pictures

Don't see anything out of the ordinary.

Interstellar can have many colors.

And the critter was probably a pod but without a pic of the little bugger it will be hard to say for sure.
