Diaporthe Carpini, Fc. 
Dead branches of water beech, Carpinus Americana. Albany. Apr. 
Diaporthe Robergeana, Viess!. 
Dead branches of bladder-nut, Staphylea trifolia. Albany. Apr. 
Diaporthe galericulata, Succ. 
Dead branches of beech, Fagus sylvatica. Sandlake. June. 
Diaporthe Neillie, 7. sp. 
Perithecia numerous, .02 to .024 in. broad, loosely and irregularly ag- 
gregated in extensive patches, immersed in the interior bark and often 
forming a slight depression in the wood, covered by the epidermis 
which is pierced by the black conical or rostellate ostiolum, the base 
often concave beneath ; asci subcylindrical, the sporiferous part about 
.0025 in. long, .0003 to. 0004 broad; spores crowded or biseriate, oblong 
or subfusiform, slightly constricted at the septum, two or four nucleate, 
.00055 to .00065 in. long, .0002 to .00025 broad. 
Dead branches of nine bark, Neillia opulifolia. Albany. Apr. 
The surface of the affected branch is rough to the touch by reason 
of the projecting ostiola. The perithecia are sometimes valsoidly clus- 
tered. 
Diaporthe marginalis, 7. sp. 
Pustules numerous, covered by the epidermis which is somewhat 
elevated ; perithecia valsoid, 8 to 15 in a pustule, nestling in the inner 
bark with no circumscribing line, the ostiola slightly emergent, black, 
usually surrounding the margin of the whitish pulveraceous erumpent 
disk; asci subcylindrical, .0025 to .003 in. long, .0004 to .0005 broad; 
spores crowded or biseriate, uniseptate, obscurely apiculate at each 
end, .0008 to 0009 in long, .0002 to .00025 broad. 
Dead branches of Alnus viridis. Elizabethtown. - May. 
In its external appearance this fungus resembles Valsa ambiens. 
In the larger pustules the ostiola form a marginal circle about the 
disk as in that species, but in the smaller ones they sometimes emerge 
centrally and obliterate the disk. 
Diaporthe sparsa, 7. sp. 
Perithecia few, minute, scattered, immersed in the wood whose 
surface is blackened; asci clavate or subcylindrical, .003 to .0035 in. 
long, .0003 to .0004 broad; spores crowded, oblong or subfusiform, 
colorless, constricted at the septum, four-nucleate, .0008 to .0012 in. 
long, .0002 to .00028 broad. Dead branches of Rhus Toxicodendron.
