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

This week’s slippery jack forecast for Hampshire, England reads 61% and looking good.

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.

Hampshire runs from the rolling chalk downland of the South Downs in the east to the open heaths and ancient woods of the New Forest in the west, drained by clear chalk-stream valleys like the Test and Itchen. Its southern edge meets the Solent coast, with tidal mudflats and saltmarsh around Southampton Water and Portsmouth Harbour. The New Forest is the standout fungal hotspot, with old pollarded oak and beech, holly, birch and conifer plantations set among heathland and grazed lawns. On the chalk further east you find beech hangers and mixed broadleaf woods, where mushrooms favour the leaf litter, mossy banks and grazed pasture edges.

Hampshire has a mild, damp oceanic climate, with relatively warm autumns and steady rainfall coming off the Channel. These soft, humid conditions keep the woodland floor moist well into autumn, which suits a long fruiting season. Hampshire is one of England’s classic foraging counties, above all the New Forest, where a huge variety of species appears from late summer through autumn. Note that picking is restricted in the New Forest itself, so foragers should know the local rules and stick to permitted ground.
