Diaporthe Carpini, Fchl. 

 Dead branches of water beech, Caiyinus Americana. Albany. Apr. 



Diaporthe Robergeana, JViessL 

 Dead branches of bladder-nut, Siajjhylea trifoUa. Albany. Apr. 



Diaporthe galericulata, Sacc. 

 Dead branches of beech, Fagus sylvatica. Sandlake. June. 



Diaporthe Neillise, n. sjj. 



Perithecia numerous, .03 to .024 in. broad, loosely and irregularly ag- 

 gregated in extensive patches, immersed in the interior barl<: 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 subcyluidrical, 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 ojjiilifolia. 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, n. sp. 



Pustules numerous, covered by the eindermis 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 snbcylindrical, .0025 to .003 in. long, .0004 to .0005 broad; 

 spores crowded or biseriate, uniseptate, obscurely apiculate at each 

 end, .0008 to 0009 in long, .0003 to .00025 broad. 



Dead branches of Alnus viridis. Elizabeth town. May. 



In its external appearance this fungus resembles Valsa anihiens. 

 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, n. 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, .0003 to .00028 broad. Dead branches of Rhus Toxica dendr07i.
