End rot, caused by Fusicoccum putrefaciens Shear, was found to 
be by far the most important rot in the Pacific coast region. This 
fungus appeared in more than 60 per cent of the total cultures which 
developed any fungus growth. The remaining species of fungi varied 
somewhat in abundance from season to season. The five species 
occurring most often were, in the order of their importance, Fusicoc- 
cum putrefaciens (end rot), Phomopsis sp., Penicillium sp. (soft rot), 
Sporonema oxycocci (ripe rot), and Ceuthospora lunata (black rot). 
The total list, however, includes nearly all of the fungi which are 
known to rot cranberries in eastern cranberry districts, as well as a 
few others of minor importance, such as Botrytis and Pleospora, which 
have not been found in the eastern sections. Perhaps the most 
striking feature disclosed by these cultures is the almost total absence
