One piece of advice with death cap. Think twice before following the call advice on that sign. There is no antidote to this day and if you don't die, you'll end up as a mushroom in a wheel chair

. I don't think there is any healthy survivor to date.
You are right Jest. They can grow in most humid caves with a fresh temperature (Champignon de Paris, I don't know the english name). Some wild species exist and the funny thing is that they look like amanita. I love mushrooms.
