Spots subcircular often confluent, from cortex of the berry, cen- 

 ters gray; margin dark or red. Acervuli subepidermal, minute, col- 

 lected; conidia oblong, ellipsoid or ovoid, 5-6 x 2-3 /*, hyaline. 



Small dark spots are produced on fruit, leaf or cane of grape. 

 These later enlarge and show white centers with dark or even red 

 borders. The mycelium lies just below the epidermis. On shoots 

 the cambium is killed and cankers develop. Two kinds of spores 

 have been found by Viala and Pacottet"' one very small and linear, 

 the other larger and in Phoma-like pycnidia. Common in the 

 eastern United States and Europe.
