Hey all. Trying shrooms for the first time in a couple weeks (pretty excited

). I told my friend to buy me an extra 10 grams for future use. But then I went on the net and tried to find info on how to store them, and I didn't find much info other than that you can't really store them for too long (they go bad...mould..etc.).
My friend told me I could just freeze them though, and they could be eaten a few months down the road and they would still be good, but with what and read on the net and the actual lack of info i could find, I'm a little skeptical now.
Can anyone give me some info on this? Can i actually freeze them, or should i just be buying shrooms only when i plan on eating them? Is trying to store shrooms a bad idea? Any info will be appreciated. I definately don't want to risk eating bad mushrooms. Thanks guys.
