there ARE a few DEADLY MUSHROOMS IN ALBERTA!!!!!!!!!!!I have found DESTROYING ANGEL (AMANITA VIROSA) please be CERTAIN OF YOUR IDENTIFICATION!!!!!!!!!!
There are several INOCYBES and PAXILLUS that cause liver failure/kidney failure. others may not kill you but are very toxic.
go with an experienced person, there is a great group in Alberta
