a given tree, a pine for example, grows over its lifespan, which may be 200 or 300 years, it associates with different mushrooms, some only colonizing the roots of young trees and others not until the tree is much older. Old growth trees may have a mushroom associated with the roots that is never found in young forests. As we gain additional knowledge of these ecological associations, we become more aware of where and when to hunt for and find certain species of mushrooms.
