Diplodia microspora B. & C. 



On Viburnum dentatum Linn. Albany, N. Y. Col- 

 lected by H. D. House, May 1915.

 microspora to exclude our material except that the conidia of 

 the latter are rather uniformly 9x3-3^ /x instead of 6-7x3 /a as 

 given in the description by Saccardo. The type of D . micro- 

 spora was collected by Curtis on Viburnum o p u 1 i - 

 folium (V. Opulus).
