Slippery Jack, Suillus luteus
The Slippery Jack gets it's name from the sticky glutinous film that covers the cap. It is also one of the few boletes with a veil that covers the yellow, tightly-packed pores of the mushroom, which later breaks away to form a skirt. Slippery Jacks are a common mushroom that are often found in close association with pine. Like their close relative, the Larch Bolete, Slippery Jacks have a mild taste, but the sticky film that covers the cap needs to be peeled-off and discarded before cooking as it can cause gastric upset in some people. This fiddly task often makes the effort far greater than the reward, although it can be dried and used in mixed mushroom recipes.
