Are Slippery Jack out in Hautes-Alpes yet?
Mushroom season in Hautes-Alpes, France is building right now, with slippery jack sitting at 33% today. The typical season runs August to November, and we’re in October now
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.
Always peel off the slimy cap skin and remove the spongy pore layer first, as both can upset the stomach. Slice and fry in butter for a soft side dish, add to risotto or stews where the texture suits, or dry the cleaned pieces and grind into a savoury mushroom powder for stocks and sauces.
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.
Hautes-Alpes is one of France’s highest and least-peopled départements, deep in the southern Alps. Glaciated peaks of the Écrins rise past 4,000 metres, while the Durance carves broad valleys and feeds the vast Serre-Ponçon reservoir. Between summits stretch high pastures and the valleys of Queyras, Dévoluy and Champsaur. Conifers rule these slopes: larch woods, a signature of the southern Alps, mix with Scots and mountain pine, Norway spruce and silver fir, giving way to beech on lower, shadier ground. The open, sunlit larch stands and their mycorrhizal roots make especially rich, well-drained ground for boletes and other symbiotic fungi.
Sheltered from Atlantic rain, Hautes-Alpes ranks among the sunniest and driest French départements, with cold winters and warm summers. Precipitation is modest, so fungi depend on late-summer and autumn thunderstorms for moisture. The season runs mainly August to October, starting high and dropping with the cooling weeks. Foraging here means climbing after the storms, hunting the damper larch and spruce stands and stream margins where moisture lingers. Cèpes and girolles reward the walk, alongside larch boletes tied to the mélèze, other Suillus under the pines, and saffron milk caps. The dry ground concentrates finds into the greenest pockets.
