Chantelle is a wild mushroom that grows under host trees -- such as Pseudotsuga menziesii -- that provide it with the sugar it needs  In turn, root filaments in the soil break down the sugar and provide nutrients and water to their hosts
The harvesting of wild mushrooms actually stimulates their growth.
 Because of this reciprocity, Chantelle, which grows under the cutting Pseudotsuga menziesii, causes severe damage to the tree
