Overview
Mycorrhizal fungus identifiable by its brown cap, pinkish-brown tubes, and the distinctive netted pattern on its stipe. Although it closely resembles some edible boletes, its notably bitter taste makes it unpalatable. This bitter quality serves as a crucial identification characteristic, distinguishing it from look-alikes.
