The probably edible Suillus quiescens
differs in that the cap does not exhibit white or olive colors when young and the stem is less glandular-dotted in maturity. The edible Suillus glandulosipes
differs most obviously in that the cap has no olive tones when young, the edges of the cap are more retentive of whitish veil tissue, and it grows in association with lodgepole pine. A number of other (non-poisonous) sticky-capped species of Suillus
are superficially similar but do not match all they key characteristics.
