Description
Suillus luteus, also known as Slippery Jack Bolete, is a medium to large bolete with a slimy, brown cap and a short to stubby stem which has brown granular dots and a well-developed ring.

Cap chestnut, rusty, olive-brown, or dark brown in color. It has a distinctive conical shape, later flattening out. It is slimy to the touch, bare, smooth, and glossy even when dry, and the cuticle is easily peeled off. Flesh whitish with yellow tinge, unchanging, moderate and soft, unchanging when cut. Pores tiny, circular, initially yellow but turn olive to dark yellow with maturity. Like the skin of the cap, they can be readily peeled away from the flesh. Tubes concolourous with pores, adnate. Spores Ocher-brown. Stem pale yellow and more or less cylindrical but may bear a swollen base. A membranous partial veil initially links the stipe with the edge of the cap. When it ruptures, it forms a membranous, hanging ring with is at first whitish, darkening with age, vinaceous-brown below and large.
