When is the best time to find Slippery Jack in Västerbotten?
This week’s slippery jack forecast for Västerbotten, Sweden reads 23% and building.
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.
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.
Västerbotten stretches from the Gulf of Bothnia coast in the east, across broad forested uplands and the Ume and Skellefte river valleys, up to the eastern edge of the Scandinavian Mountains in the west. The terrain is a low-relief mosaic of rolling hills, lakes, rivers and extensive peatland mires, rising gradually toward the fells. The region is overwhelmingly taiga: dense boreal forest of Scots pine and Norway spruce, mixed with birch on damper and more open ground. Mushrooms favour the spruce woods and mossy mixed stands, the birch margins, and the edges of mires and forest tracks.
This is a cold subarctic, continental climate with long snowy winters and short, fairly cool summers. Most rain falls in late summer, and that combination of late-summer showers and lingering moisture in the moss is what triggers the main fungal flush. Foraging here means quiet, sparsely populated forest with little pressure and the freedom of allemansrätten. Expect chanterelles, porcini, birch boletes and russulas from roughly August into September, often overlapping with the cloudberry harvest on the mires.
