The not-recommended (but widely eaten) Laetiporus gilbertsonii
grows on hardwoods rather than conifers, but otherwise has an identical appearance. It has been implicated in symptoms of swollen lips, dizziness, vomiting, and nausea in some individuals. The inedible Pycnoporus cinnabarinus
differs in that it is red or reddish, is not banded with yellow, and the edge of the cap is not soft and undulating.
