BLM lets you collect reasonable amounts of some renewable plant resources for noncommercial use outside developed sites. BLM guidance names mushrooms and says small personal amounts can be collected in most areas. Check with the local field office.

43 CFR 8365.1-5(b) allows collecting reasonable amounts of commonly available renewable resources such as flowers, berries, nuts, seeds, cones and leaves for noncommercial purposes, except at developed recreation sites or where prohibited and posted. The regulation does not name mushrooms, but BLM's public guidance says you can collect small amounts of mushrooms for personal use in most areas. Other collection of forest products falls under 43 CFR part 5500, which may require a permit. Rules can vary by field office; check with the land manager.
