surrounded by an elevated margin and a brownish-red border ;

MACROSPORIUM TOMATO, Cke. 
Decaying fruit of tomato. Menands. October. 
PILACRE ORIENTALIS, B. & Br. 
Dead bark of alders, Alnus incana. Elizabethtown. September. 
In our specimens the sporiferous branches are sometimes elon- 
gated and flexuous and the young plant wholly white, in which 
respects they differ from the typical form of the species. But the 
stem soon becomes cinereous and finally the whole plant is 
umber-brown. Young plants sometimes grow from the base of 
old ones, sometimes from the head. 
GRAPHIUM SORBI, N. sp. 
Spots generally small, oue to two lines broad, orbicular, definite, 
reddish-brown ; stems hypophyllous, rather stout, equal or slightly 
tapering upward, the component flocci diverging and colorless at 
the apex ; spores oblong, hyaline, .0008 to .001 inch long, .00025 
to .0008 broad, sometimes with two to four minute nuclei. 
Living leaves of mountain ash, Pyrus Americana. Adirondack 
mountains. July. 
ISARIOPSIS ALBOROSELLA, Sacc. 
Living or languishing leaves of chickweed, Cerastium vulgatum. 
Keene. July. 
I find only uniseptate spores in our specimens. 
FUSARIUM LYCOPERSICI, Sacc. 
Fruit of the tomato. Menands. Angust. 
A malady affects the fruit of the tomato. In the vicinity of 
Albany, the past season, the first ripening tomatoes were found 
almost. invariably to be soft and decaying. A brown or discolored 
epot, usually located at the flowering end of the fruit, appears to 
be the origin and center of the disease. This spot often makes its 
appearance while the fruit is yet green. This Fusarium soon 
develops on this spot, appearing in the form of minute pallid 
dots, or in more effused patches which are of a pinkish or an orange 
hue. With advancing age it assumes a more or less brownish hue. 
If the affected tomato be cut open its inner flesh often exhibits a
