When will Porcini appear in Uppsala?
Porcini usually come up in Uppsala from August to November, and right now they’re at 75% and running strong.
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.
Keep fresh caps in a paper bag in the fridge and use within a couple of days, as they spoil and get wormy fast. Slicing and drying is the classic long term method; they also freeze well if briefly sauteed first.
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.
Uppsala sits on the flat, fertile Uppland plain, low-lying farmland threaded by the Fyrisån river and the long gravel eskers left by the ice age. South and east the land gives way to the bays of Lake Mälaren and the Baltic coast, while gentle forested rises take over to the north. Boreal conifer forest dominates, mostly Norway spruce and Scots pine mixed with birch, aspen and alder. Mushrooms favour the mossy spruce stands, the damp birch edges and the bogs and pine heaths common across reserves like Hågadalen-Nåsten and Norra Lunsen.
The climate is humid continental, with cold, snowy winters and mild summers. The decisive rains come in late summer and early autumn, and it is this damp warmth that triggers the main fungal flush. Foraging here is easy and rewarding thanks to the right to roam, with chanterelles arriving around midsummer and porcini, funnel chanterelles and other autumn species following into October. Spruce and birch woods within easy reach of the city make Uppsala a generous region for beginners and seasoned pickers alike.
