This seemed to be due not only to the smaller number of 
spores, but also to lesser pigmentation. 
Gloeosporium yielded a heavy gelatinous growth upon most 
of the media containing mangold, celery, and carrot decoc- 
tions, but there were considerable differences in the amounts

gave abundant fruiting when sugar was added in the presence 
of nitrate, and less in all other cultures. On the celery-con- 
taining solutions there was less difference in the amount of 
fruiting observed, and the mangold was intermediate in this
