Shouldn't you be careful? Correct me if I'm wrong, but aren't some strains of these mushrooms not edible at all, even after they're dried?
Don't try the "Amanita Pantera", they look like "A.Muscaria(fly agarics)", but have gold tops with white spots. I tripped VERY hard and had a blood pressure incident that shut down my kidneys for a while, had to do 2 rounds of dialysis before they kicked in again. As for A.Muscaria, check Erowid for trip reports, usually people roast them a little bit before eating them. As for the buzz, I got no "euphoric" hit, just nasty visuals, severe nausea, disorientation. A little(but only a little), like K. As for dosage, there are many subspecies, make tea, drink slowly.
