Safety first
Many edible mushrooms have toxic lookalikes, and some of those can be fatal. Have any mushroom identified in person by a local expert before you eat it.
If someone may have eaten a wild mushroom, call US Poison Control at 1-800-222-1222 or 911 right away. In Canada, call your provincial poison centre or 911.
