Grows in mycorrhizal partnership with trees, especially under pine, spruce, birch, beech and oak, on well drained soil. Found in conifer and broadleaf woodland and along woodland edges and tracks.
One of the finest edible mushrooms, with a deep savoury nutty flavour. Excellent fresh in risotto, sauces and fried in butter, and it dries very well to concentrate the flavour for stocks and soups.
Can be confused with the bitter bolete (Tylopilus felleus), which has a darker net on the stem, pinkish pores when mature and a strongly bitter taste, and with red pored boletes. Avoid any bolete with red or orange pores or flesh that stains strongly blue.
Jönköping County sits on the southern Swedish highland (Sydsvenska höglandet), a rolling upland of forest, glacial moraine and countless lakes and peat bogs. Its eastern edge meets the great Lake Vättern, with the city of Jönköping at the lake’s southern tip. The county is dominated by Småland’s coniferous forest, mostly Norway spruce and Scots pine mixed with birch, with patches of beech and oak in the south. Chanterelles and porcini thrive in the mossy spruce stands, along forest edges and on the blueberry-covered slopes.
Being raised highland, the region is cooler and noticeably wetter than the surrounding lowlands, catching heavy rainfall that keeps the forest floor damp well into autumn. These moist, mild conditions make it reliable mushroom country from late summer onward. This is classic Småland foraging territory: expect generous chanterelles, funnel chanterelles and Karl Johan (porcini) in the spruce woods, with vast tracts of open access forest under the right to roam (allemansrätten). The season builds from August and often runs strong through October.
