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.
About the species. Edible when correctly identified and thoroughly cooked. Older specimens become soft and spongy and are often damaged by larvae, so young, firm fruitbodies are preferable.
