sad mushrooms

I woke up and there was a fucking giant mushroom in my pot, about 3 inches tall.
it happend over night, that fucker was not there the day before... are my other plants in trouble? what can I do?

haha that happened to my homies plants he ended up pullin em out cuz they were stuned i dnt think it was frm the shrooms tho

Dig it up, don't pull it out or cut it, and then continue on. (The mushroom not your plant)
Maybe spray a little anti-fungal plant spray on the soil.
