In the Americas, this species can be confused with R. dissimulans. The latter differs however, in its closer lamellae, larger spores with higher ornamentation and dry pileus. Other field characters of these taxa include the compact and firm flesh which is white at first, but soon changes to red (on the stipe of the basidioma at center left) before becoming gray to black. Taxa of this group frequently play host to Asterophora.
