  2. Matsutake (tanoak) mushrooms harvested under these provisions should have the stem cut from the cap within one inch of the cap or be cut in half vertically through both the cap and stem. Cutting should take place at time of picking and prior to mushrooms being placed into any container or transported from the immediate harvest site.
  3. No Matsutake mushrooms less than 1 ½ inch cap diameter should be harvested. Older and decomposing mushrooms (all species) shall be left in place.
  4. When gathering mushrooms leave the soil, woody debris, vegetation, and mushroom’s mycelial mat in an undisturbed condition. Use of rakes, leaf blowers, or other ground disturbing techniques is prohibited.
  5. Mushrooms should be harvested individually by cutting, twisting/plucking, or with the use of tools no greater than 1 inch blade width.
  6. Collection of mushrooms is permitted only on BLM-administered lands.
  7. Persons collecting mushrooms shall clean up all trash and litter generated by their activities. WARNING! Existing trash/debris may contain hazardous materials. Please notify your local BLM office.
  8. Drive only on existing roads and park so as not to block traffic. Comply with all road closures. Do not drive on non-surfaced roads during periods of wet weather.
  9. Persons collecting mushrooms must comply with all State and Federal laws/regulations concerning fire prevention requirements and fire closures. Persons must abide by all state, county or local laws or rule regulating the collection of personal use mushrooms.
