the decay of the wood, were collected. This was due, in part at 
least, to the fact that these structures are rather conspictious and 
thus attract attention, so that individuals remove them from the 
trees. Further, the careful pruning operations carried out by 
the Park workmen naturally tend to the removal of these fun- 
gous structures before they have attained any appreciable size. 
However, many of the trees showed evidences of various de- 
cays due to the development of the mycelium of the various 
higher fungi. The decayed areas generally were associated with 
injuries to the trees. Where a limb had been broken off or the 
pruning operations improperly carried out, the fungi gained en- 
trance and produced the decay of the underlying tissues, 
Nevertheless, in several cases the fruiting structures of various 
polypores were collected. A well-grown specimen of Fomes ap- 
planatus (Pers.) Wallr. was collected at the base of a large privet 
plant. This shrub, like most of the other privets in the park, 
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 body of the Fomes 
was found close to the ground, growing from one of the larger 
stubs. This particular stub, however, was also producing 
branches bearing living green leaves. 
One well-developed specimen of Daedalea quercina (L.) Pers. 
was found on the English oak. The fruiting body was located 
at a point on one of the large limbs where previously a smaller 
limb had been pruned off. Sufficient care had not been taken, 
however, to prevent the cut surface from exposure to fungus in- 
vasion. The Daedalea had doubtless gained entrance at the 
pruned surface, and by subsequent growth had produced decay 
back for a considerable distance. In fact, the decayed region 
extended back practically to the main trunk. 
everal fully developed specimens of Polyporus gilvus Fr. 
were collected on the soft maple and on the blue beech or Amer- 
ican hornbeam. The fruiting bodies covered a considerable area 
of the trunk of the maple several feet from the ground. In this 
case also the growth was associated with an injury due to the 
breaking off of a large limb. On the American hornbeam, the 
main stem was attacked and bore several fruiting bodies. The
