Is there any risk of wild, potentially dangerous, mushrooms colonizing your garden?
What you learn is how to positively identify the mushrooms you intend to produce/eat. It doesn't take long. I've only had alien mushrooms show up once.
Maybe it would cost 10 times as much as the wood chips themselves… small batch spore bakeoffs…
I tried growing a little wine cap bed once, and it hadn't gone well. Perhaps it was the chickens pecking at it, can't say. I do still get wine caps on occasion, but they have migrated to more far-flung parts of the yard.
You probably already know this, but for anyone reading, there’s a species of mushrooms that looks kind of like morels that is poisonous, potentially fatally so.

There are plants that can screw up your life if you touch them, but people sort of have the two threat levels flipped in their heads. The scariest thing a fungus can do to your insides is horrible, but an insect or animal can do the same but also you die screaming. So... be careful out there kids. And don't go to Australia.
