⚠ Before you pickWild fungi may be taken in small quantities for your own use (§39(3) BNatSchG) — but not in nature reserves or national parks, on closed land or on farmland in use, and never for sale (§39(4)). In Bavaria this right is anchored in Art. 141(3) of the state constitution and is limited to locally customary amounts; the competent authority is the district nature-conservation authority (untere Naturschutzbehörde). Local signs and ordinances come first.
