COMMON MUSHROOMS OF THE UNITED STATES 395 Photograph by George Shiras, 3d "A TRAGEDY IN TIIE FOREST" Armillaria mellea is here shown at its destructive work. This tree is doomed. This species of fungus is also shown as the upper figure of Color Plate VI and on opposite page. If you chop off the mushrooms, others will soon replace them, for they are simply the fruit of a parasite infesting the tree (see page 392 and the bracket fungus, page 409).
