Bronze boletus is a rare mushroom, found in mixed (with oak, beech) forests and on moist humus soils, mainly in southern Russia, in summer and in the first half of autumn, singly or in groups of 2-3 specimens. Can also be found under pine trees.
You can confuse the bronze boletus with the edible Polish mushroom (Xerocomus badius), it has no net on the leg, and the flesh sometimes turns blue; the very high quality Boletus pinophilus may also be similar, but it is more common and has a wine or brownish red cap and larger size. Finally, in deciduous and mixed forests, you can find the semi-bronze Boletus (Boletus subaereus), which has a lighter cap.
