occidentalis. The first one is due to an un- 
described species of Polyporus. Large holes 
are formed in the heartwood of the trunk, 
one above the other. Each is full of my- 
celium and has a thick white lining, con- 
sisting of wood fibers from which the lignin 
has been removed, leaving the pure cellu- 
lose. The fruiting part forms on the out- 
side of the trunk, forming around a dead 
branch. It has been reported so far from 
Kentucky and Tennessee. Thesecond form 
of destruction is more widely spread. It is 
due to a Polyporus, probably P. carneus. 
Long pockets are formed in the heartwood 
of a tree, filled with a brown bitter wood, 
which has characteristic properties. The 
sporophore forms in the branch holes on 
the trunk ; they have a flesh-colored hy- 
menium and are quite common. 
Attention is called to the fact that a very 
large per cent. of the individuals of Juni- 
perus Virginiana are defective because of one 
or other of these fungi.

SULLIVANT DAY. 
Wepnespay, August 23d, was taken by 
the Botanical Section for a bryological me- 
morial to do honor to Sullivant and Les- 
quereux. The meeting was held in the 
Botanical Lecture Room which had been 
appropriately decorated with mosses and 
ferns and hung with portraits of Sullivant 
and Lesquereux loaned by the members of 
both families present. The tables sur- 
rounding the room were filled with books 
and pamphlets on bryological subjects, and 
the spaces ander the windows with micro- 
scopes showing rare or type specimens of 
SCIENCE.

mosses and hepatics. The walls were hung 
with photographs of botanists whose names 
are associated with American bryophytes, 
as well as plates and illustrations from 
original publications. 
The meeting was called to order with 
Dr. Chas. R. Barnes in the chair and 
Professor Kellerman as Secretary, who 
welcomed the large number of members 
and guests present and opened the session 
with some preliminary remarks on the 
work done on the flora of Ohio by Joseph 
Sullivant, William S. Sullivant, Riddell 
and others, and exhibited pressed speci- 
mens, framed of Sullivantia Ohionis, Loni- 
cera Sullivantii, Solidago Ohions, S. Riddellit, 
and other rare plants. Duplicates of these 
were distributed in sets after the adjourn- 
ment of the session. Professor Kellerman 
then read Dr. Gray’s tribute to Sullivant 
from the Supplement to the Icones. Twelve 
North American mosses have been named 
for Sullivant ; specimens of these with orig- 
inal drawings were loaned from the Sulli- 
vant collection in the Gray Herbarium at 
Harvard University ; duplicates of these 
species were presented by the Herbarium of 
Columbia University to the Ohio State Uni- 
versity and microscopic slides were made by 
Mrs. Britton who gave a short account of 
them. 
Dr. Barnes then read a brief biographical 
sketch of Leo Lesquereux, exhibiting the pic- 
ture of his father’s home at Fluellen where 
he fell down a mountain in search of plants, 
one of the causes of his subsequent deaf- 
ness, a misfortune which in the end proved 
a blessing, as it enabled him to devote 
himself with undisturbed serenity to the 
study of fossil plants and mosses. Several 
of his paleontological works were not pub- 
lished until after his death and many of the 
illustrations were made by his granddaugh- 
ter, Miss Ahrhart, who acted as his inter- 
preter and assistant. A brief account of 
these posthumous publications was pre-
