Boletus edulis - Wikipedia

Heavy-metal contamination Boletus edulis is known to be able to tolerate and even thrive on soil that is contaminated with toxic heavy metals, such as soil that might be found near metal smelters . The mushroom''s resistance to heavy-metal toxicity is conferred by a biochemical called a phytochelatin —an oligopeptide whose production is induced after exposure to metal. [82]
