® Control. 
The inoculations clearly show that the fungus will cause a 
rot of cacao and papaya fruit, and a severe infection and the 
death of Hevea rubber seedlings. Since the same hosts are 
attacked by the strain of Phytophthora faberi Maubl. isolated 
from cacao fruits it can be stated, from the evidence furnished 
by cultural studies, that the organism from cacao is identical 
in this respect with the strain of Phytophthora isolated from 
coconut bud rot. 
MORPHOLOGY OF PHYTOPHTHORA FABERI MAUBL. ISOLATED FROM 
COCONUT 
GROWTH ON VARIOUS MEDIA 
The fungus grows well on potato agar, oat meal agar, corn 
meal, and macerated young corn. A dense white, more or less 
felty growth, is produced on each. In the small number of tests 
thus far conducted the spore formation appeared to be slightly 
different on each medium. Chlamydospores are produced in
