Mushroom foraging laws in Wyoming
Compiled from official sources; not legal advice. Rules change. Confirm with the land manager or the agency before you pick.
Summary
Wyoming's rules do not name mushrooms for state parks or state trust land. State parks require the superintendent's permission to remove "plant matter," and trust land allows only casual day uses, with commercial use needing a special use lease. Wild-picked mushrooms under the state food rule must be individually checked by an approved identification expert. Federal lands follow their own rules.
Public land
State parks: removing or disturbing "plant matter" needs the superintendent's prior permission, and digging or removing any "tree, shrub or plant" is prohibited. Mushrooms are not named and the rules do not define these terms, so ask the park first. State trust land: the public may use legally accessible land for "casual recreational day uses" such as hiking and rock hunting; mushroom picking is not named, so it is unclear. Federal lands follow their own rules.
Permits
State parks require the superintendent's prior permission to remove or disturb plant matter. Whether that applies to mushrooms is unclear. On state trust land, activities outside casual recreation need a temporary use permit or special use lease from the Office of State Lands and Investments.
Selling
State parks prohibit gathering fruits and berries for sale; mushrooms are not named. On state trust land, commercial recreational use is prohibited unless under a special use lease.
Morel sales
Wyoming's food rule (Agriculture Dept., Chapter 3, Food Care) says mushrooms picked in the wild must come from sources where each mushroom is individually inspected and found safe by an approved mushroom identification expert. Exceptions: cultivated wild species grown in a regulated operation, and packaged wild mushrooms from a regulated processing plant.
