Hey D,I was told by a Friend,That Native Americans Used to use Poison Mushrooms for Fishing,As it is told,there is a Special Amanita,It is Called Amanita Panthorina-Identified by it's Color/Traits:Yellow or Orangeish Yellow with Black spots on the cap.The more common Amanita Muscaria(Death Cap)was not used as the Toxin was diferrent.The Panthorina's were Dried,Pulverized into powder,then spread out over calm water,or in a pond,& The next day fish would be floating on the surface,1/2 alive,but Easy to collect.This Mushroom also was used in combo with some other poison,for Arrows to shoot Deer with but,the info I was told,Pertained to Fish only.For Survival Purposes,It could be an Option,Of course it doesn't sound viable,since you'd have to dry the stuff,& How long would it take to dry?I was told The Amanita Panthorina Mushroom,was Very Difficult to find,have you seen any of this Description? Good Luck with the Foraging!
