When will Brown birch bolete appear in Västra Götaland?
Mushroom season in Västra Götaland, Sweden is building right now, with brown birch bolete sitting at 30% today. The typical season runs June to October, and we’re in July now
It fruits after warm summer or autumn rain, typically when daytime temperatures sit around 12 to 20 C and the ground stays damp. A good soaking followed by mild, humid days a week or so later usually brings them up.
Greyish to dull brown cap up to about 15 cm, with a spongy pore surface underneath that is whitish then greying (not gills). The tall stem is whitish and covered in small dark brown to blackish scales, and the white flesh is soft, barely changing colour when cut.
Edible and mild in flavour but the flesh turns soft and slightly slimy when cooked, so it is best used young and firm. It works in mixed mushroom dishes, soups and dried for stock rather than as a fried mushroom on its own.
Easily told from other Leccinum such as the orange birch bolete by its dull brown cap. It has no deadly lookalikes, but as a bolete only ever pick firm specimens, since old soft ones cause stomach upsets, and avoid any bolete with red or orange pores and blue-staining flesh.
Västra Götaland stretches from the rocky skerries and granite islands of the Bohuslän coast inland across the flat farmland of the Västgöta plain to Lake Vänern and the wooded uplands of Tiveden and the table mountains around Billingen. It is a varied county where the open sea, big lakes and rolling forested ridges all meet. Spruce and Scots pine dominate the inland forests, mixed with birch, oak and beech in the milder southwest, while damp lakeshores and mossy ridges add wetter habitats. Chanterelles favour the mossy spruce and pine woods, while the calcareous soils around Falbygden and the broadleaf stands support porcini and many other species.
The county has a mild, maritime climate near the coast, growing slightly more continental towards Vänern and the eastern uplands. Autumn is reliably damp with frequent rain off the North Sea, which keeps the woods moist well into October. Foraging is a popular pastime here, helped by the Swedish right of public access (allemansrätten) that lets you pick freely in most forests. Expect a generous chanterelle and porcini season from late summer through autumn, with the richest finds in the mossy conifer woods inland and the lime-rich soils of the Västgöta plain.
