When is the best time to find Slippery Jack in Northumberland?

Mushroom season in Northumberland, England is building right now, with slippery jack sitting at 34% today. The typical season runs August to November, and we’re in October now

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.

Grows in conifer woods, almost always with pine, on sandy or poor soil and often along forest tracks and clearings. Common in young plantations and appears in groups.

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.

Northumberland is a sparsely populated upland county where the rounded Cheviot Hills rise along the Scottish border and broad sweeps of heather moorland roll east toward the North Sea. Between the hills lie the river valleys of the Tyne, Coquet and Till, while the coast stretches into long sandy beaches, dunes and rocky headlands. Kielder Forest, the largest planted woodland in England, blankets the western moors in dense Sitka spruce, lodgepole pine and larch, classic ground for boletes and milkcaps. Lower down, scattered oak, birch and beech woods along the valleys and the old policy woodlands around country estates offer richer mixed-broadleaf habitat.

The climate is cool and damp, with reliable rainfall over the western uplands where the moors and forests catch the wet westerly weather. The drier eastern coast still sees mild, moist autumns that keep the ground productive well into the season. Expect a tale of two grounds: vast conifer plantations like Kielder for spruce-loving boletes and chanterelles, and the valley broadleaf woods and coastal grasslands for a wider mix. It is remote, uncrowded country, so a forager has space to roam but should plan for changeable upland weather.
