Annual Report of the State Botanist. 29 



Diaporthe rostellata Nitsch. 



Stems of blackberry, Ruhus villosus. Menands. July. Also on 

 dead stems of Ruhus odoratus. Salamanca. 



This may be considered a noxious fungus. The plant found 

 on blackberry stems had surrounded the stem \\'ith a pallid spot 

 and had killed all the plant above this spot. The asci are often 

 only four-spored. 



Diaporthe Americana Speg. 



Dead branches of cucumber tree. Carrollton. September. 



The published description of this species is incomplete the 

 spores in the specimens from which it was made being immature. 

 In our specimens they are narrowly fusiform, acute at each end, 

 quadrinucleate, .0006 to .0007 in. long, .00016 broad. 



Massaria epileuca B. & G. 

 Dead branches of red mulberry, Morus rubra. Saugerties. May, 



'' Caryospora minor n. sp. 



(Plate4, flgs. 18 to2l.) 



Perithecia .014 to .021 in. broad, slightly sunk in the matrix, 

 subglobose, even, black ; asci four- to eight-spored, subcylindrical, 

 .006 in. long, .0008 broad; spores fusiform, pointed at each end, 

 uniseptate, slightly colored, .0018 to .002 in. long, .0005 broad. 



Pericarp of hickory nut. Albany. 



This differs from C. putaminum in its smaller perithecia which 

 are not concentrically grooved and in its shorter, narrower and i^aler 

 spores which are more numerous in an ascus. 



Metasphaeria nuda n. sp. 



Perithecia superficial, ovate or conical, submembranous, scattered 

 or few collected together, black, the walls parenchymatous and blue 

 under the microscope ; asci about .003 in. long, .0005 broad ; spores 

 crowded or biseriate, fusiform, triseptate, colorless, .0007 to .0008 in, 

 long, .00024 broad. 



Dead stems of millet, Panicum miliaceum. Menands. October. 



The species approaches 31. Famcorum, from which it is distinct 

 by its superficial perithecia and shorter spores. The superficial 

 character of the perithecia would remove the species to Zignoella, 

 but the texture is not carbonaceous, and it has therefore been placed 

 in Metasphaeria.
