Is it Birch Bolete season in Østfold right now?

Birch Bolete usually come up in Østfold from June to October, and right now they’re at 46% and looking good.

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.

Summer to autumn, mainly June to October.

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.

The flavour is mild and the flesh turns soft and can go slimy when cooked alone, so it is best used in mixed mushroom dishes rather than as a star. Slice and fry firm young caps with onions for an omelette, add to soups and stews, or dry and grind into a mushroom powder for seasoning.

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.
