FIG. 35. A decaying tree trur' the cause of the death of the tree by the appearance of the several fungi (j>n>l>al>ly .\m,in;tii muscurin). It is not unusual to find trees showing signs of disease and, finally, even dying, and it is not until the death of the tree that the mature fungus makes its ap]»-.nance. For some years the mycelium of the fungus has been working its way into the tissues not only of the bark but of the wood, sapping it of its vitality. When there is no longer any food supply the fungus produces its fruit; the spores, being scattered by either the wind or through the agency of birds, are carried to other trees and find entrance into wounds, where they germinate and repeat their destruction.—From a photograph by Henry Troth.
