When is the best time to find Slippery Jack in Merseyside?
Slippery Jack usually come up in Merseyside from August to November, and right now they’re at 55% 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.
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.
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.
Merseyside is a low-lying coastal county wrapped around the Mersey Estuary and Liverpool Bay, ranging from the city of Liverpool to the wide tidal sands and dune systems of the Sefton Coast around Formby and Crosby. Inland it gives way to gentle farmland and pockets of mossland, with the Wirral peninsula reaching out between the Mersey and the Dee. Woodland here is fragmented but varied: the Sefton Coast is famous for its pine plantations behind the dunes, while inland and estuary parks hold mixed broadleaf stands of oak, birch, beech and willow. The coastal pinewoods and dune slacks are prime ground for fungi, alongside damp willow carr and grassy parkland.
The county has a mild, damp maritime climate, with cloud and frequent rain rolling in off the Irish Sea and few hard frosts. This steady moisture and gentle autumn warmth keep the ground productive well into late season. Merseyside rewards a coastal forager: the Formby and Ainsdale pinewoods and dune slacks are a genuine draw, with parkland and estuary woods adding broadleaf finds. Much of the land is urban or protected nature reserve, so check access and local rules before picking.
