How are Slippery Jack doing in Aberdeenshire this October?

The best time for slippery jack in Scotland is August to November, with the peak normally in the middle of that range. Today they’re at 38% and building in Aberdeenshire

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.

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.

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.

Aberdeenshire stretches from the heather moors and rounded granite hills of the eastern Cairngorms down through the fertile farmland of the Howe of the Mearns to a long North Sea coast of cliffs, dunes and fishing harbours. The valleys of the Dee and Don thread through the county, linking upland glens to the lowland plain around Aberdeen. Native Scots pine and birch survive in old Deeside woods like Glen Tanar, while extensive conifer plantations of spruce and pine cover the lower hills. Mixed broadleaf stands of oak, beech and birch along the rivers, together with mossy pine forest floors and grazed pasture, give chanterelles, ceps, hedgehog fungi and waxcaps their habitats.

The east coast is drier and cooler than the Scottish west, with crisp clear spells, sea haar rolling off the North Sea and sharp autumn frosts. Rainfall is moderate but reliable, and the damp, cool autumns suit a long fungal season. Expect a classic Highland-edge mix: pine-wood boletes and chanterelles in the Deeside glens, hedgehog fungi and ceps under conifers, and jewel-coloured waxcaps on the old grasslands. Much of the land is open access under Scottish right-to-roam, though the season runs a little later and cooler than further south.
