Unknown neon green

[Sam22]

Bought this mushroom a couple days ago and it’s foot has moved from the plug to the rock and now I can see this bright green thing that would of been underneath. Any ideas what it is?

If that thing doesn’t move, it could be a softie/leather, like a Kenya tree.

No it doesn’t move seems to have a foot attached to the plug like the mushroom did

Possibly a baby yuma?

That’s what I first thought but colours are completely different if it’s a baby of the orange one in the pic

I think it’s either a baby or dying shroom. The zooanthallae is probably so concentrated it’s giving it a green color.
That’s what my new or shriveling ones (usually dying) have looked like despite being pink shrooms.

I'm voting on a baby shroom, or dying one.

It doens't have to be of that mushroom, could have been from a different one.
