Are Slippery Jack out in Kronoberg yet?

The best time for slippery jack in Sweden is August to November, with the peak normally in the middle of that range. Today they’re at 45% and looking good in Kronoberg

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.

In the same pine woods and season look for other Suillus such as larch bolete and weeping bolete, plus saffron milkcaps and the occasional bay bolete or porcini on richer patches. False chanterelles and various brittlegills often share the same acidic ground.

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.

Kronoberg sits on the Småland highlands, a gently rolling inland plateau of low ridges, glacial moraine and stony, acidic soils. There is no coastline; instead the county is threaded with countless lakes, bogs and rivers, including Lake Åsnen and the Mörrumsån. Dense coniferous forest dominates, mostly Norway spruce and Scots pine on thin moraine soils, mixed with birch, and patches of oak and beech on richer ground. Mushrooms favour the mossy spruce stands, pine heaths and the damp margins of bogs and lakes.

The climate is cool and humid, with some of the higher rainfall in southern Sweden thanks to the upland setting. Wet, mild late summers and autumns keep the forest floor reliably moist for fungi. Expect classic Småland conifer foraging: chanterelles, porcini and other boletes under spruce and pine, with funnel chanterelles often lasting well into a damp autumn. Forest is plentiful and access is open under allemansrätten, though acidic ground means fewer calcareous specialists.
