Idaho state guide
Idaho 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 lodgepole burns, cedar draws, and mountain meadows.

Bitter Bolete (Tylopilus felleus) is a realistic state-level profile for Idaho, where foragers look for it in hardwood and mixed forest on acidic soils tied to Douglas-fir duff, alder bottoms, and wet cedar-hemlock forests. This page narrows the North American pattern to local terrain and seasonality instead of relying on generic continent-wide copy. a classic edible-look-alike that teaches caution. It is generally considered inedible or not worth collecting for the table. Toxicity planning matters because not poisonous, but its intensely bitter flesh ruins meals even in tiny amounts.
