pected in such a locality, but wood-destroying kinds, both sap- 
rophytic and parasitic, mostly belonging to the Polyporaceae, 
were quite abundant. 
The principal wood-destroying species observed were, Poro- 
daedala Pini, on pitch pine; Pyropolyporus igniarius, on species 
of oak; Pyropolyporus Robiniae, common on all the black eens 
trees seen; Fomes populinus, chiefly on maple ; E// 
common on several hard-wood species ; nee Tee on 
hemlock ; Laetiporus speciosus, common on oak and a few other 
lus versicolor, on various hardwoods; Fistulina hepatica, on 
chestnut; and Ayduum septentrionale, on black gum. Daedalea 
guercina was not seen. As beech and birch were very rare in 
the valley, no specimens of A/fvingia fomentaria were collected, 
although it must be common at other elevations. Avimellaria 
mellea, a very destructive root-rot, was known to be present in 
abundance, but the sporophores were only beginning to appear. 
chestnut tree is of immense importance in the Biltmore Forest, 
being cut in great quantities annually for lumber and for tannin 
extract. It is said that the successful employment of chestnut 
wood pulp, now a waste product from the extract factory, for the 
making of paper, would increase the value of Pisgah Forest, 
with its wealth of chestnut timber, one hundred per cent. This 
tree is very sensitive and is dying in many parts of the forest 
from the effects of the chestnut borer and the disturbance of the 
natural forest conditions, but, fortunately, this new disease, so 
abundant and destructive about New York, has not yet been 
introduced at Biltm 
Besides the ee mentioned in the above list of wood- 
destroying species, Aurantiporus Pilotae was twice collected on 
decayed oak logs, Cyctoporus Greenet was found in two places 
along the roadsides attached to underground roots, and A/icropo- 
rellus dealbatus was common in open thickets on the roots of 
various members of the heath family. Coltricia cinnamomea was 
very abundant on the banks along the roads and trails, while C. 
perenmis was found only once and C. obesa twice.
