 The pores are pale yellow, round, 1–2 mm wide, and do not change color when bruised.The stipe is white to pale yellow, dry, solid, not bruising, and pruinose (having a very fine whitish powder on the surface).A characteristic feature of many "Suillus" species are the glandular dots found on the stipe—clumps of hyphal cell ends through which the fungus secretes various metabolic wastes, leaving a sticky or resinous "dot".
