What's up with this mushroom

It's hard to tell in the pic, but the area from about 9 o'clock to 11 o'clock is quite a bit darker than the rest of it

Looks like a fold I've had a few do this before they split so you may be about to be a proud owner of 2 shrooms

That one is really small, the damn things just pop up around the tank. Some of them aren't even on rocks, they're growing up out of the sand

I've got some on glass sand these pop up everywhere lol
