A western slippery jack that looks like Suillus brevipes but usually shows a partial veil, either as tatters on the cap margin or as a fibrous ring or sheath on the stem. The bald, slimy cap is brownish yellow to yellow-brown and fades to tan. It grows mainly with lodgepole pine.
Edibility is not documented separately in the sources consulted. Its close relative S. brevipes is edible, but this species is not recommended until confirmed.
