Now I wonder if this thing only exists in Hungary, but here there are lots of mushroom checking stations, typically near markets, where an expert checks your bag of mushrooms. They have an official license from the food safety authority and there is a central register for these mushroom experts.

My dad always brought the stuff we picked there, it was close by enough and it's just a totally normal thing here.

I would imagine it would be a nightmare to do this in the US due to legal liabilities.
