A fly agaric mushroom (Amanita muscaria) and a cone of Eastern White Pine are side by side on a New Hampshire forest floor in October. A sapling of Eastern Hemlock sends sprays over the mushroom, and wintergreen adds a splash of red. The pine and fungus form a partnership in which underground filaments of the mycorrhizal fungus invade the roots of the pine, and both provide essential nutrients to each other. Both partners have their reproductive structures above ground.
