"Suillus" is a genus of fungi in the sub-order Boletales, commonly called "slippery jacks" because of the often slimy caps. They are distinguishable from other boletes by usually having partial veils in immature forms and annuli thereafter, sometimes glandular dots on the stipe, and large pore openings that are often arranged radially. They principally grow in association with conifers.

Members of this genus are often hard to distinguish from other boletes, as a few have dry fibrils or scales (S. lakei) and the sliminess of the cap can vary dramatically with environmental conditions. Several species (ie "S. brevipes") have no veil or glandular dots. The name is derived from the Latin sus, meaning "pig".

Edibility

Most "Suillus" species are edible but none are highly esteemed. However some of the suilloids are known to cause idiosyncratic allergic reactions in some people. In some species, the slimy cap coat acts as a purgative when consumed and should be removed before cooking.

A few edible examples from this genus include:

*"S. americanus" - Chicken-fat Suillus
*"S. bovinus" - Jersey cow mushroom
*"S. brevipes" – Short-stalked Suillus
*"S. granulatus" – Dotted-stalk Suillus
*"S. grevillei" - Larch Suillus, Larch Bolete
*"S. luteus" - Slippery Jack (many "Suillus" species are called by this common name)
*"S. placidus" - White Suillus
*"S. pungens" – Pungent Suillus
*"S. subluteus" - Slippery Jill
*"S. tomentosus" – Tomentose Suillus
*"S. tridentinus"
