Raulin's fluid. (PI. XL, fig. 11.) Inoculated 13. vii. 14. 



20. vii. 14. In all tubes colourless mycelial growth in liquid. This 



growth has not yet reached the surface on 22. vii. 14. 



Tubes shaken up so as to get growth to the surface. 

 27. vii. 14. Surface growth good. 

 31. vii. 14. The following regions in all the tubes: 



(1) Leaden-grey (Plate 353. 1) 4-7 mm. wide. 



(2) Pure white growth creeping up sides of tube. 



(3) Between the above — a very light yellow tint. 



6. viii. 14. Majority of chlamydospores 16-5-19*8/x diameter. Following 

 regions : 



(1) Leaden-grey (Plate 353. 4). 



(2) Eosy flesh (Plate 134. 4) 3 mm. wide. 



(3) Pale buff (Plate 64. 4). 



(4) Above this pure white creeping up sides of tubes. 



Growth below warty and of a fleshy colour. 



Turnip tubes. (PI. XL, fig. 15.) Inoculated 1. viii. 1914. 

 5. viii. 14. Growth dense, greyish, fluffy to cottony. Conidia sparse 

 with septa indistinct.

21. viii. 14. Growth 3-4 mm. thick, in places on surface greyish yellow. 



In some tubes raised hummock-like white bodies. In 

 places along the glass, bronze-yellow (Plate 34. 3). 

 Just above cotton-wool there is most frequently a 

 leaden grey ring (Plate 353. 4) which may be yellowish 

 in patches. Conidia abundant. 



II. Growth in the Absence of Free Oxygen. 



To test whether the fungus is able to grow in the absence of free 



oxygen, fermentation tubes containing the following media were 



inoculated: Uschinsky's fluid, Raulin's fluid, liquid beef-broth, liquid 



beerwort. Two tubes of each medium were inoculated, by removing
