That's a psilocybin mushroom. Eat that. That won't hurt, but isn't enough for a trip.
It's very nice to see a magic mushroom growing next to a cannabis plant.
Do not try them! your picture was not good enough to truly ID them, it's not worth taking a chance...you could get either very sick...or even die!...no need to worry about them hurting your plants because they are not harmful to them, just pick them out and discard if you don't like them there.
Yes, that's the kind of shroom that will either kill you or at the very least, make you quite sick. Actually though, I have no clue what kind it is, but DON'T EVER EAT ANY SHROOMS THAT YOU CAN'T IDENTIFY 100%. If it doesn't "blue" up when it's bruised, it's not a psilocybin mushroom.
