Illinois state guide
Illinois does not have one simple statewide rule for wild mushroom collection. Personal-use gathering is often permitted on some national forests, state forests, or wildlife lands, but state parks, preserves, and sensitive habitat units may prohibit removal entirely. The practical rule is to verify the exact managing agency before picking, especially in bottomland hardwoods, oak woods, and pasture edges.
