Tiny Mushroom in the pot

[NYCorchidman]

So, what I thought was just one of the bark chips in my paphiopedilum potting mix grew a little taller over the course of a few days and now I see it is a mushroom of some kind.

I took a closer look and there are two more in the same pot. These look they are attached to each other.

Should I leave them or pull??
Or eat them in my soup?

Oh, by the way, the ugly brown mark on the leaf was done by a big slug, can you belive it??

I thought it was a fungal rot and sprayed like crazy only to find out one night this slimy gross thing was just scratching the leaves all over! Yep, I killed it right on the spot.
