Mushroom foraging laws in Iowa
Compiled from official sources; not legal advice. Rules change. Confirm with the land manager or the agency before you pick.
Summary
Iowa's Natural Resource Commission rules say the public may harvest mushrooms on its lands during the hours the areas are open. Selling wild mushrooms to restaurants or farmers markets is allowed only for eight listed types, each inspected by a certified identification expert. Federal land and county or city land follow their own rules.
Public land
Iowa Administrative Code 571-54.1 says the public may harvest mushrooms and asparagus on lands under the jurisdiction of the Natural Resource Commission during the hours the areas are open to the public. Nut, fruit and berry gathering is not allowed in state preserves unless the preserve's management plan allows it; that rule does not name mushrooms. Counties and cities may set their own rules.
Permits
The mushroom rule (571-54.1) does not mention a permit.
Limits
The rule gives no number or weight limit.
Selling
Under Iowa's food code amendment (481-31.1(5)), a food establishment or farmers market licensee may sell or serve only listed wild-harvested mushrooms, each individually inspected by a certified wild-harvested mushroom identification expert. The buyer must keep a written buyer specification for 90 days, and a consumer advisory is required. The rule does not apply to cultivated or packaged mushrooms from an approved processing plant. Iowa State University Extension says sellers must hold a current Wild-Harvested Mushroom Certificate, renewed every three years.
Morel sales
Morels (Morchella spp.) are one of eight wild-harvested mushroom types on Iowa's list that may be sold.
