Like Suillus brevipes, S. tomentosus is very common and abundant in the PNW. Its cap is viscid when fresh and typically has a covering of grayish, yellowish, reddish brown or bright red fibrils or fibrillose scales over an orange-yellow to yellowish background. The flesh is yellow and usually turns bluish on exposure. The tubes are yellow and the pores are angular, brown to yellowish, and stain blue when injured. The stipe is conspicuously glandular dotted and similar in color to the cap. There is no veil. Suillus variegatus is a European kissing cousin.
