You either like it or not, this is a mushrooms that divides people. Slimey, easily recognised by the cap, great in soups and Asian dishes.
You will find it in Pine plantation on the Souther Highlands of NSW or on the Blue Mountains together with the Saffron milk caps, quite often creating its own areas.
There are two main varieties of Suillus in this environs, one is the slippery jack (Suillus luteus) and the other is the Weeping bolete (Suillus granulatum). The main difference is the presence (S. luteus) or abscence (S. granulatum) of a 'ring' on its base. They are both edible and some might even say excellent.
It is common practice to remove the slimey skin on the cap form this mushrooms before cooking as it might cause stomach upset on sensitive people, but apart from that, go for it.
