Destructive Toadstools and Bracket Fungi. — Some Toad- stools attack the roots of trees and cause the disease called Root Rot. This disease occurs on a number of fruit trees, such as the Apple, Plum, Cherry, and Peach, and on many shrubs and forest trees. In Figure 343 is shown some Toadstools which have destroyed an Apple tree. The Toadstools usually cause the death of the roots, and this results in killing the tree. The mycelia of the Toadstools probably enter the roots through Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Martin, John N.
