You can eat the caps and the stem, no evidence to suggest there is less active ingedient in the stem. You can make a tea out of it or put them on a pizza. I like to dry them out and powder them, then put the into caps. thy aren't as potent but it makes for easy storage and you get less queasiness. There is a few good facebook goups and forums like Psilocybin hunters AUS/NZ and Shroomery.org , perfect reading material and location specific information on both :)
