Deadly Amanita mushrooms will test as “safe” for most of these. In other words, DO NOT use these to suss out which mushrooms are poisonous….

From the upcoming “Seriously Poisonous Mushrooms of North America” Zoom class

I wouldn’t use these methods if I were you.

A mushroom is toxic if:

…a silver coin blackens if placed in water with the mushroom    

…the mushroom curdles milk

…it’s cap skin is difficult to remove

…it turns a clove of garlic blue or black when cooked together

…if it grows on dung (the ubiquitous grocery store Button Mushroom would be flagged 

    as toxic)

…if its flesh turns a different color upon slicing

…if its odor is unpleasant
