in color and less abundant in growth, and formation of spores, 

 (Plate 4, Fig. 4). Lack of glucose had a very marked effect. 



The Conidia_ 



The conidia vary in length from 31 to 57 microns, the 

 average being 43. These measurements do not include the beak. 

 The latter varies greatly. The end beak of a chain may be very 

 long, while the spores within the chain may have almost none.

Sometimes spores are produced an the end of a long beak (Plate 

 I, Fig. 10). The width of the spores was from 9 to 22 microns, 

 the average being 13. Thus the spores are about three times as 

 long as wide, not including the beak. They are almost always
