This week’s oyster forecast for Uppsala, Sweden reads 45% and looking good.
It is one of the few choice mushrooms that fruits in cool weather, often after the first autumn frosts and through mild winter spells when temperatures sit around 5 to 15 C. A drop in temperature following damp conditions is the main trigger, so look in the days after cold rain rather than after summer heat.
It grows on dead and dying hardwood, especially beech, poplar, willow, oak and aspen, appearing on standing trunks, fallen logs and stumps rather than on the ground. It favours damp deciduous and mixed woodland, parks and riverside trees where dead wood is plentiful.
Look for overlapping shelf-like clusters on tree trunks and logs, often high up, and check the underside for decurrent gills that run down a short off-centre stem. Pick young specimens that are still firm and pale, as old ones turn tough, leathery and prone to insect larvae.
Can be confused with the angel’s wings (Pleurocybella porrigens), which is white, thinner and grows on conifer wood and has caused poisoning, so check the substrate and colour. The mild bitter oysterling (Panellus) and lung oyster are smaller and less fleshy but not dangerous.
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.
