when you eat them fresh they are all wet and soft. There also wiegh a lot more because of all the water wieght inside them. When dried they are a little cruchy and wiegh like 1/10th of the fresh ones. 1 gram dried equals 10grams fresh you will eat about the same amount but the fresh ones wiegh a lot more. To have a good trip eat about 3-4 grams of dried or 30-40 grams of fresh. If you have fresh i would just dry them out and eat them
Mushroom Master pretty much nailed it, but I'd like to add that heat and oxygen destroy Psilocybin and Psilocin so eating them fresh would be stronger. I'm saying that 30 grams of fresh would be stronger than 3 grams of dried.
