Store as dried fruits with a dessicant packet and a hand warmer (oxygen scavenger) in freezer. Half of the weird mushroom flavor/odor is from it being improperly dried and stored. I dry mine to cracker-dry, and you really don't get a lot of flavor or texture from them.
If they're still hard to consume, shred them and extract into tea. Psilocybin is water soluble. Some like to add lemon juice, as it supposedly hurries the conversion of psilocybin to active psilocin (not sure how true this is). Tastes a little different but is relatively quite palatable.
You're conflating Mushrooms with (Mu)Shrooms it seems to me. Shrooms are not primarily about the taste. And you can very well make Shrooms storable for up to several years.
(Granted, it's been years since I last ate magic mushrooms. I loved the way they tasted, but I don't think it's fair for someone who doesn't like they way they taste to have to gag them down just for a trip. I can still remember how they tasted, and the wonderful visions I had.)
Mushrooms also don't store well.
Extracting psilocybin so it can be served in a more palatable and easily stored form is a good thing.
