Crepidotus crocophyllus can be distinguished by its yellow to orange immature gills, chestnut-brown to tawny velvety cap, and lack of a stipe. The cap is similar in Crepidotus mollis, but the latter has young gills that are white, becoming grayish white then brown at maturity, ellipsoid spores, and hyphae that lack clamp connections. Phyllotopsis nidulans is also similar but has an orange tomentose cap, orange gills that produce white spores, and a strong unpleasant odor (although the odor can sometimes be absent).
