It fruits after warm late-summer and autumn rain, typically when day temperatures sit around 10 to 20C and the ground stays damp. A good soaking followed by mild nights usually brings flushes within a week or two.
Strictly associated with pines, so look in conifer plantations and natural pine woods, often on sandy or poor acidic soil. It favours forest edges, paths, grassy verges and young plantations rather than deep shade.
Late summer through autumn, roughly August to November.
Use fresh within a day or two as the slime makes it perish quickly; peel and clean before chilling. It dries well once peeled and de-pored, and the dried slices or powder keep for months in an airtight jar; it can also be cooked and then frozen.
Always peel off the slimy cap skin and remove the spongy pore layer first, as both can upset the stomach. Slice and fry in butter for a soft side dish, add to risotto or stews where the texture suits, or dry the cleaned pieces and grind into a savoury mushroom powder for stocks and sauces.
Other Suillus boletes such as the larch bolete (Suillus grevillei) and weeping bolete, all of which are also edible, so there are no dangerous poisonous lookalikes. The slimy brown cap, yellow pores and ringed stem set it apart from any toxic gilled mushroom.
