Fig. 1. A section through the host showing the presence of the parasite and 

 its effect upon the host. X 125. 



Fig. 2. A fragment of a plant showing the tortuous creeping filament, a 

 true hair, and several typical gametangia. X 125. 



Streblonema penetrate S. and G. 



Fig. 3. A section through the host perpendicular to its surface showing the 

 apparent disorganizing effect of the penetrating portion of the Streblonema. 

 X 125. 



Fig. 4. Individual plants separated from the host. X 250. 



Streblonema scabiosum S. and G. 



Fig. 5. A section through the host perpendicular to its surface showing the 

 relation of the two plants. X 250. 



Streblonema Porphyrae S. and G.

 X 125. 



Streblonema myrionematoides S. and G. 

 Fig. 7. Showing plants in various stages of development, X 250. 



Streblonema aecidioides f. pacificum S. and G. 



Fig. 8. A section tlirough an "aeoidium" and perpendicular to the surface
