On leaves of Urechites lutea Britton in Porto Rico. 
In our specimens the spores are somewhat larger than those of 
typical specimens, measuring 4.8-9.6 X 2.4 /x. Phyllosticta neri- 
cola has hyaline spores, 8-10 X 3 m. and differs only in color and a 
slight variation in the size of the spore. This species is distinct 
from Phyllosticta Nerii in the size of spores, those being much 
larger, 15-18 XS-^M- 
Associated with this is an undescribed species of Colletotri- 
chum having perithecia surrounded with setae, and with hyaline, 
ovate-oblong spores.
