Magic mushrooms, in particular, love cow dung as a growing medium.
That being said, fungus tends to be nigh indestructible. The guy boiled it before injection which really speaks to just how hardy those spores can be.
No, he poured boiling water over the mushrooms - big difference. Plenty of time for boiling water to cool before killing all of the spores.
This is a myth. Most magic mushrooms grow in wood, moss, dirt, etc. The media just likes hyping up p. cubensis first whatever reason.
