Where to look: brown birch bolete
A field over the measurement network. The colour here is for the leading species at each point, not for this one; a per-species layer is computed for one region so far.
Brown Birch Bolete in Utrecht: where to look

Brown Birch Bolete: the species in brief
How to tell it
A slender bolete with a grey-brown to brown cap and a pale stem covered in dark scab-like scales. The flesh may slowly turn grey after cutting.
Where it grows
Always associated with birch. It occurs in woodland, heaths, parks and along woodland rides wherever birch is established.
In the kitchen
Good fried, in soups or dried. Older pore layers are often removed because they become soft during cooking.
Nutrition
Low in calories with a modest amount of protein.
