where a large limb had been broken off some time previously. 
The broken branch had been pruned off and the surface covered 
with some tar preparation. Nevertheless, decay occurred at the 
edge of the wound and the fungus formed a fruiting body. 
A few other specimens of this same fungus were collected at the 
base of some large privet shrubs. These plants had been pruned 
back, leaving a large number of stubs a foot or more in length. 
From these stubs the new leaf-bearing branches of the shrub had 
developed. The fruiting bodies of the fungus were collected 
close to the ground, attached to the large stubs, which, however, 
still produced leafy branches. 
Several typical specimens of Polyporus giluus Fr. were collected 
on the silver maple, blue beech (American hornbeam) and cherry. 
The fruiting bodies of this fungus were taken from the main 
trunk of a silver maple in 1916. These covered a considerable 
area of the trunk and were associated with an extensive decay of 
the wood. Following the removal of these brackets in 1916 the 
Park workmen cut away the decayed wood and applied a tar 
preparation. In 1917, however, additional fruiting bodies were 
observed growing from the same part of the tree. The fruiting 
bodies of the same fungus were abundant on the main trunk of 
a cherry, associated with extensive injuries. On the American 
hornbeam the main stem was attacked and bore several brackets 
of the fungus. 
The large lilac and privet shrubs were more or less severely at- 
tacked by Polystictus versicolor (L.) Fr. Most of the larger 
shrubs of these plants had been cut back, leaving short stubs six 
inches to two feet in length, and from these the new leafy 
branches had arisen. It was discovered that, in a large per- 
centage of cases, these old stubs were severely attacked by the 
fungus. The wood of these stubs was more or less completely 
disintegrated and the fruiting bodies of the fungus were gen- 
erally present. Sometimes a part of the wood in the stems was 
decayed and bore numerous brackets, while the other side was 
still sound and produced long leafy branches. The common oc- 
currence of this fungus on the older lilac and privet shrubs indi- 
cates that it is a serious enemy and special precautions should be 
taken to prevent its spread on these plants. Since the fungus is
