Mushroom harvest rules
Rules vary
State parks
No single rule applies; each state park agency sets its own. Check with the park or its state agency before you pick.
State park rules are set by each state's agency and sometimes by the individual park. Use the state government directory to find the parks agency, then check the park's rules or ask a ranger. See this site's state pages for what we have verified.
