XI. B, 6 Wade: Cultivation of a Pathogenic Fungus 283 



Figs. 37 and 38. Comparing two-day growth on nutrient banana agar and 



on banana cylinder. 

 Fig. 39. Firm "thimble" of growth, seven days on nutrient banana bouillon. 



Drawn up in tube and turned to demonstrate firmness. 



40. Growth on plain bouillon, one week. Cottony aerial growth col- 



lapsed except over two small areas. 



41. Development of mycelial segments on agar, without oxygen. Early 



vacuolation. X 450. 



42. Similar to above. Several very refractile hyalinized segments. 



Extreme vacuolation of mother cells, which show growth from 

 side. X 450. 



43. Old mycelium from depths of bouillon. Highly refractile granules 



formed within the sheath. A delicate septum, to be seen only 

 in occasional senile hyplue, is indicated. X 450. 

 Figs. 44 and 45. Two terminal bodies (chlamydospores) found in hanging- 

 drop preparations. That in fig. 45 is not attached to the 

 adjacent filament. X 450.
