376 Biffen. — A Fat-Destroying Fungus. 
EXPLANATION OF FIGURES IN PLATE XIX. 
Illustrating Mr. Biffen’s paper on a Fat-Destroying Fungus. 
Fig. I. (a). Microconidia germinating. 
( b ). A strand fraying out into conidia-bearing hyphae. 
Fig. 2. (a). Apex of a hypha which has not yet produced conidia. 
(d). A hypha branching, showing the ‘ proteid reserves.* 
Fig. 3. Daughter-nuclei separated by a vacuole. 
Fig. 4. A chain of chlamydospores, from the hanging-drop-culture from which 
Fig. 1 was drawn fifteen days previously. 
Fig. 5. (a). Young macroconidia on hyphae standing away from a stroma. 
(£). Stages in development. 
(^). Stages in germination after twenty-four hours at 16 0 C. in yeast- 
extract and gelatine, and after forty-eight hours. 
Fig. 6. A portion of the mycelium formed by 5 c. seven days later. 
Fig. 7. The development of the stroma from a culture on coco-nut endosperm, 
three weeks old. 
Fig. 8. Median longitudinal section through one of the sterile perithecia, 
showing the parenchymatous wall and the plexus of hyphae within it. 
Fig. 9. Section through a block of coco-nut endosperm, showing the alternating 
bands of infected and uninfected tissue. The infected tissue is shaded to represent 
the grey colour of the original. The stroma is beginning to form on the upper 
surface. The dark line on the lower surface represents the brown testa. 
Fig. 10. Longitudinal section through a fortnight-old culture on coco-nut 
endosperm to show the distribution of the mycelium. On the right of the figure 
the growth at right angles to the original direction has commenced. 
Fig. 11. The branched and swollen hyphal endings about to grow through 
gelatinized transverse walls.
