The edible and common Gomphidius smithii
differs in that it is smaller (3-6 cm broad) and the lower part of the stem does not have bright yellow flesh, except sometimes at the extreme end. The edible but less common Gomphidius largus
is sometimes considered a variety of this species. It differs in being larger (up to 20 cm broad). The edible but poor-tasting Gomphidius oregonensis
differs in that the cap is dingy salmon in color and it grows in clusters where the stems are fused at the base.
