It's never quite that simple. It may die , it may just be adjusting. DON'T WORRY, mushrooms are great they live through anything(almost), just give it time, it will probably open
is that a red mushroom?
All my red shrooms just died. but green and blue shrooms are all fine. and others corals are all fine too.(even tourch and leathers)
there's sth like to kill red shroom?
