Slippery Jack Cheshire

Updated 24 September 2026

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

Slippery Jack usually come up in Cheshire from August to November, and right now they’re at 56% 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.

It has a distinct membranous ring or partial veil remnant on the stem, an unusual feature among the slippery-capped Suillus boletes.

A decent edible with a mild flavour, good in mixed dishes, soups and sauces rather than as the star. Always peel off the slimy cap skin, which can otherwise cause loose stools, and discard the spongy pore layer on older specimens.

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.

Cheshire is dominated by a broad, flat lowland known as the Cheshire Plain, broken only by the low sandstone outcrop of the Mid-Cheshire Ridge running through Delamere and Beeston. Much of the county is patchwork dairy farmland dotted with hedgerows, ponds (the famous ‘meres’) and lowland peat bogs. The county’s woodland highlight is Delamere Forest, a mix of Scots pine, oak and birch on sandy soils, alongside scattered oak-and-beech estate woods, riverside alder and willow, and damp wooded fringes around the meres and mosses. These habitats favour boletes and chanterelles under conifers and oaks, with grassland waxcaps on old pastures.

Cheshire has a mild, moist maritime climate, sheltered somewhat from the western hills but still reliably damp, with consistent rainfall through autumn that keeps the lowland soils and leaf litter moist for fungi. Foraging here centres on Delamere Forest and the lowland mosses rather than uplands, so expect classic broadleaf and conifer woodland finds plus rich grassland fungi on unimproved meadows. Most land is farmed and privately owned, so foragers should stick to public access areas and footpaths.
