tree, however, was still alive with fairly vigorous foliage 
branches. 
The lilacs and the privets were badly infected with Polystictus 
versicolor (L.) Fr. Most of the larger shrubs of these plants 
had been cut back, leaving short stubs six inches to two feet or 
more in length, and from these new leafy branches had devel- 
oped. It was noted that in a large percentage of the cases, these 
old stubs were badly attacked by Polystictus versicolor. The 
wood was badly decayed and the brackets of the fungus were 
very common. In many cases, a part of the wood had been de- 
cayed and bore the brackets, while the other side of the stem 
was still alive and bore long leafy branches. It is evident from 
the common occurrence of this fungus that it is a serious enemy 
of the older privet and lilac shrubs, and special precautions must 
be taken to prevent its development. Special care must be taken, 
when pruning the old shrubs back, so to treat the cut surfaces 
that the fungus may not gain entrance. 
This same fungus was collected on other plants. One of the 
most striking cases was found on an English haw. This plant 
had branched close to the ground, and consisted of two main 
branches each about five inches in diameter at the base. They 
were about twelve to fifteen feet high. One branch was entirely 
dead. The wood was badly decayed and the surface quite coy- 
ered with the brackets of Polystictus versicolor. The brackets 
extended from the ground to practically the tip of the branch. 
This branch had been injured some time previous. Through the 
injury the fungus had gained entrance and ultimately killed the 
entire branch. 
A polypore was collected at the base of several large wild 
cherry trees in the Park. The structures, however, had not ma- 
tured sufficiently to make an accurate determination. Several 
trees bore one or more of these imperfectly developed fruiting 
bodies which were associated with decay in the trunk of the trees. 
Schizophyllum alneum Schr. was collected on dead branches 
of Ailanthus in the Botanic Garden and on sumac in the Park. 
It is probable, however, that these trees had died from other 
causes and that Schizophyllum alneum was a secondary develop- 
ment,
