Suillus cavipes is sometimes placed in the genus Boletinus. Like S. ochraceoroseus it is associated with larch, wherever it occurs in the PNW. Both of these species have dry, fibrillose-scaly caps similar to that of Suillus lakei, and a veil that may leave material on the edge of the cap and a ring or ring-zone on the stipe. S. cavipes usually has a reddish brown cap although, at times, it can be pale yellowish brown. The pores are pale yellow, often angular or elongated, and sometimes decurrent. The stipe is yellowish above the ring and fibrillose and colored like the cap below it. The name “cavipes” (Latin for “hollow foot”) refers to the hollow stipe which is an important characteristic for identifying the species.
