A good way to ensure the dispersal of mushroom material is to get your jar of honey ready, fill a pot 1/2 to 3/4 of the way full with water, place the jar lid on the bottom of the pot and place the jar on top of the lid, then heat the water until the honey in the jar becomes more watery (but not too hot, you don't want to get rid of your magic), then mix in your powdered mushroom material. This method just makes it easier to ensure that the mushroom powder mixes in more evenly and doesn't clump together, and will also help you stir it without all the magic sticking to your spoon.
It's an excellent storage method as long as you ensure your mushroom material is 100% dry before mixing it into your honey as I believe water will cause your honey to begin to ferment if allowed to sit for a while. Also, make sure you use 100% natural honey, I don't think artificial honey preserves the psilocybin/psilocin as well. Have fun! :D
