This fungus upon the different media used showed striking differ- 
- ences in: number of setae, varying 
from none to abundant; number of 
spores, varying from few to many; 
color, varying from pale to almost 
black. 
On CBA growth was scant; acervuli 
small, setae absent. 
On CBA+ammonium lactate and 
CBA+sodium asparaginate, growth 
was about as in CBA, except that 
numerous black setae were present. 
On CBA+ammonium _§lactate+ 
starch, the acervuli were larger, more 
numerous, with numerous large black 
setae. 
On CBA+sodium asparaginate+ 
ammonium lactate, there were a few 
setae. 
On CRA + sodium asparaginate 
+ glucose, black setae were numerous.
