Is this “normal?”

So I named this plant Smorgasbord, and besides the few mealy bugs I’ve had to deal with, I quite like it!

However, I noticed the fungi/mold a little while ago and wondered if it’s okay to leave it in there or if I should repot it with new soil. I noticed the fungi maybe a month or so ago, and not sure how long it was like that before I noticed. So the plants aren’t dying and actually look healthy… but I wanted to get a second opinion. lol thanks!
