Late summer to autumn, roughly August to November.
A good edible with a mild, pleasant flavour, used in much the same way as cep in soups, sauces and fried dishes, and it dries well. The flesh may discolour slightly when cut but this does not affect cooking.
It can be confused with the cep (Boletus edulis), which is also edible, but the bay bolete is darker brown and its pores bruise blue-green whereas cep pores do not. No common European bolete with which it is confused is deadly, but always check that the pores are not red or orange and that any blueing is slow, to rule out the few unpleasant blue-staining boletes.
Kalmar stretches along Sweden’s southeastern Baltic coast, forming the eastern edge of Småland together with the long, flat island of Öland across the Kalmar Sound. It is mostly low, gently undulating country: forested inland with scattered lakes and marshes, giving way to a fertile coastal plain and Öland’s open limestone alvar. Coniferous forest of pine and spruce dominates the mainland interior, but Kalmar is Sweden’s most oak-rich county, with noble broadleaf woods of oak, beech and hazel groves along the coastal plain and on Öland. These old deciduous stands, along with mossy spruce forest and birch edges, are the prime ground for mushrooms.
This is one of the driest, sunniest corners of Sweden, sheltered by Öland and tempered by the Baltic, often with early-summer drought in a normal year. Good fungal flushes therefore depend heavily on late-summer and autumn rain rather than steady moisture. Expect a season that hinges on rain: in a wet autumn the oak woods and conifer forest can be excellent, while a dry summer can hold things back. The mix of rich deciduous habitats and ordinary spruce forest gives variety, from chanterelles and porcini to oak-loving specialities.
