When will Slippery Jack appear in Schleswig-Holstein?
Slippery Jack usually come up in Schleswig-Holstein from August to November, and right now they’re at 53% 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.
Cap is chestnut to dark brown, smooth and very slimy when wet. The underside has fine pale yellow pores rather than gills, and the stem carries a distinct ring with small brown dots above it. The flesh is pale and the smell is mild.
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.
Scan the ground near any pine, especially along sandy tracks and clearings where they often appear in groups. Pick young firm caps, since older ones go soft and waterlogged, and carry them separately because the slimy cap coats everything.
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.
