Is it Porcini season in Östergötland right now?
The best time for porcini in Sweden is August to November, with the peak normally in the middle of that range. Today they’re at 75% and running strong in Östergötland
Fruits after warm, humid spells when soil temperatures sit in the mid teens Celsius and a good soaking rain follows a warm period. A typical trigger is heavy rain after several warm days, with flushes appearing roughly one to two weeks later.
Late summer into autumn, roughly August to November in Britain and Ireland.
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.
Östergötland is split across the middle by the broad, fertile Östgötaslätten plain, with the wooded south Swedish highlands and their many small lakes to the south and the rocky Kolmården ridge to the north. Lake Vättern forms the western edge, while the east breaks up into the islands and skerries of the Baltic archipelago. The richest fungi grow in the highland conifer forests of spruce and pine, in mixed woods on the moraine ridges, and in the unusually old oak and beech stands such as the Tinnerö oak landscape near Linköping and Omberg by Vättern. Calcareous soils on the plain edges and the limestone of Omberg favour a particularly broad range of species.
The climate is mild and humid for the latitude, tempered by Vättern and the Baltic, with most rain falling from late summer into autumn. These warm, wet late-season spells are exactly what trigger the main mushroom flush. A forager here can move between several habitats in a short distance, from chanterelles and porcini in the conifer highlands to grassland and oak-meadow species on the limestone soils. Allemansrätten gives open access, and the patchwork of forest, lake shore and plain edge makes for productive, varied picking from August through October.
