Thats how the magical ones are in Washington! Theyre literally everywhere so the law states you're not allowed to forage for ANY mushrooms without a permit. Here in oregon you can possess up to a gallon (weird unit of measurement, trust me i know) of wet mushrooms per person. Including psilocybins, and any spores, as you can have them for scientific research purposes. Only illegal once dry.
The permits are literally only 6$ for 10 days of unlimited foraging though. Its super lax over here.
