PLATE s 
A. —Sample of com free from internal paratic fungi germinating on nutrient dextrose 
agar. The kernels were surface-disinfected with o.i per cent bichlorid of mercury in 
50 per cent alcohol for one minute, then washed twice in sterile water and immediately 
placed on the sterile medium. 
B. —Sample of com carrying internally two fungi. The black growth is an As pet- 
aillus sp. which is present to the extent of 100 per cent;’the white fungus, indicated 
by tiie arrow, is Fusarium moniliforme which is present to the extent of 40 per cent. 
The presence of the Aspergillus sp. probably indicates that the com had poor curing 
conditions. 
Somewhat reduced.
