The poisonous and/or acrid L. repraesentaneus
, L. torminosus
, L. rufus
and L. scrobiculatus
are similar in appearance. They differ in that the cut flesh exudes a white rather than orange milk and does not eventually discolor to greenish. The not-recommended L. helvus
differs in that the cap has a salmon/pink color, the spore deposit is tan, the cut flesh oozes a colorless, watery milk, and the odor is liquorice-like. The edible but rare L. rubrilacteus
differs in that the cap and latex are more reddish.
