The Forest Service lists mushrooms as a special forest product. Rules and permits are set by each forest, so check with the district office before you pick.

The Forest Service lists mushrooms among special forest products. Federal regulation prohibits removing a forest product except as authorized (36 CFR 261.6), and prohibits selling or exchanging a forest product obtained under free use. Personal-use rules vary by national forest: the Olympic National Forest, for example, needs no permit for incidental personal picking and sets one gallon per species per year, while other forests set their own limits or permits. Commercial picking needs a permit, as the Olympic page states. Contact the district office. Wilderness areas and closures may add restrictions.
