22 in this locality on Acer rubrum, Carya glabra, Cornus florida, 
Fagus grandifolia, Liriodendron tulipifera, Quercus prinus, Sas- 
safras variifolium, Vaccinium sp., and Vitis sp. without success. 
On April 18, the following hosts were inoculated in Virginia: Acer 
rubrum, Betula nigra, Benzoin aestivale, Carpinus caroliniana, Carya 
glabra, Cornus florida, Fagus grandifolia, Liriodendron tulipifera, 
Prunus serotina, Quercus alba, Ulmus americana, and Vitis sp. 
Each host was inoculated in from four to six places. Of these, 
pycnidia were produced only on Acer rubrum, Carpinus, and Lirio- 
dendron. A. similar series was made on the same hosts in the same 
place on May 27. Inoculations on one tree of Quercus alba showed 
undoubted evidence of parasitism and is described below. 
On July 9 and 11 from five to fourteen inoculations were made 
on each of the following hosts at Woodstock, N. Y.: Acer rubrum, 
Betula alba, Carya ovata, Fagus grandifolia, Fraxinus americana, 
Hamamelis virginiana, Juglans cinerea, Kalmia latifolia, Nyssa syl- 
vatica, Ostrya virginiana, Populus grandidentata, Prunus serotina, 
Rhus typhina, Quercus rubra, Salia sp., Sambucus canadensis, and 
Sassafras variifolium. Pycnidia appeared on Acer rubrum and 
Ostrya only. The fungus made considerable growth on two plants 
of Rhus typhina, partly girdling branches one-half inch in diameter 
and producing distinct fans. The fans were, however, much smaller 
than those usually found in Castanea. Inoculations were made at 
Avon, Conn., July 15, on Acer saccharwm, Betula alba, Carya glabra, 
Cornus florida, and Ostrya virginiana. Pycnidia developed only 
on Ostrya. The successful inoculations with Endothia parasitica 
are shown in Table VII.

" 1 Inoculations producing pycnidia are classed as successful. 
Tt must be noted that while pycnidia were produced in the cases 
listed as successful, there was no indication of parasitism, nor did 
the growth extend beyond the tissue injured by the cut except in 
Quercus and Rhus. 
Out of about 400 inoculations with Endothia parasitica on hosts 
other than Castanea, about 70 of which were made on different
