Suillus luteus is the type species of the genus Suillus. It is a most widespread summer and autumn fungus. S. luteus is a common fungus indigenous to coniferous forests of Europe, Asia and North America, and introduced to New Zealand and southern Australia.
The common name Slippery Jack is an obvious reference to the slimy nature of caps of this mushroom during wet weather, although they are not particularly sticky during warm dry spells when they tend to be become smooth.
Suillus luteus is an edible mushroom although some authors regard it as one of low quality.The species is considered a delicacy in Slavic cultures. Some people may have allergic reactions or digestive problems, so some authors recommend discarding the glutinous cuticle and tubes before cooking.
