Perithecia numerous, .03 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 

 w^hich is pierced by the black conical or rostellate ostiolutn, the base 

 often concave beneath ; asci subcylindrical, the sporiferous part about 

 .0025 in. long, .0003 to. 0004 broad; spores crowded or biseriate, obloog 

 or subfusiform, slightly consti'icted at the septum, two or four nucleate, 

 .00055 to .00065 in. loug. .0002 to .^0025 broad. 



Dead branches of nine bark, JVeiUia opuUfoUa. 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.

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, 

 Tisually 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 loug, .0002 to .00025 broad. 



Dead branches of Alnus viridis. Elizabeth town. May. 



In its external appearance this fungus resembles Valsa amhiens. 

 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.

 surface is blackened; asci clavate or subcylindrical, .003 to .0035 in. 

 long, .0003 to .0004 broad; spores crowded, oblong or subfnsiform, 

 colorles?, constricted at the septum, four-nucleate, .0008 1o .0012 in. 

 long, .0002 to .00028 broad. Dead branches of Rhus Toxicodendron.
