A secondary conidium of the second type produced from a conidiophore which is neither capillary nor of 









the usual type. 



Fig.

a spore. 



Fig. 





125. 



A hypha of germination of the usual type, from a primary conidium, has sent up a capillary conidiophore 









at the tip of which a secondary conidium of the second type is beginning to form.

Two hyplial bodies taken from a mass filling the abdomen of Aphis. 



Figs. 



128- 



-140. 



Two hyphal bodies lying side by side previous to conjugation begin to show slight prominences on their 









upper inner sides. 



Fig. 





129. 



These prominences have become gametes which have come in contact with one another midway betweeu 









the two hyphal bodies. 



Fig. 





130. 



The partition wall between the gametes has wholly or partially disappeared and a bud has begun to ap. 



pear rising upwards from their point of union.
