A++. A+. A???? I have heard that they grade them only on appearance, but this doesn't make any sense to me. How could you possibly tell how potent amanitas are just from appearance? Also, is there any noticeable difference between Siberian and Washington Amanitas? Are the highest priced Amanitas usually the vendor's best? I ordered some "A Siberian" grade Amanitas from an [edited] seller and felt zero effects from dosing 7 grams. I'm getting some A+ Washington grade this week from an online vendor with a nice proffessional looking website. Should these be better?
