Best time to pick Amanita muscaria

[kLiik]

When is the best time? Some say when the mushroom cap is upturned and the mushroom is sporating. Other say you get the best effects from those that are completly dried on the stalk. They are golden in color as opposed to mostly yellow/some red/a bit golden sporating ones. I suppose the worst ones are the young red ones that look most beautiful. If i pick them too you early, even when dried, they still have some red in them, especially in the middle of the cap.
Which brings me to another question, what is the color of muscimol and ibotenic acid? Muscimol golden, ibotenic acid red?
