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.
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.
Pick young, firm specimens because older ones quickly become spongy, waterlogged and maggot-ridden. Confirm the birch association, the brownish cap, the white pores that bruise and the scaly stem, and slice each one to check the flesh before adding it to your basket.
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.
