THE CHIGNON FUNGUS. 383 
a number of cells become detached from the outer or 
sporular form, and at once move actively about. These 
small cells indicate an active growth by subdivision, and 
a fruitful source of propagation; they subsequently be- 
come the cells seen in Fig. 3. Certainly this variety of 
fungus so far described is the most active growth I have 
come across in my researches, and I have been enabled to 
germinate it most successfully, so as to set all questions 
as to its nature completely at rest. Placed under favor- 
able circumstances in water, the spores (Fig. 3) enlarge 
considerably, and the mycelial filaments increase also ; but 
there is at this time to be observed a very remarkable 
occurrence, though not in all cases. Some of the large 
cells in Fig. 1, have become filled with smaller cells; and 
in others, in addition to these, processes have been put 
_ forth from the circumference of the walls in a radiating 
manner; in other cases the enlarged cells have two long 
cilia attached to them, by which they move about rap- 
idly, whilst a part of the hair, previous to this free from 
the fungus, has become dotted all over by minute cells 
similar to those seen in the in- Fig. 4 
terior of the larger ones. All 
this is seen in Fig. 4. 
But more than this, I have 
observed most distinctly large 
cells filled with smaller cells, 
furnished with exceedingly deli- 
cate radiating processes and put- 
ting forth pseudopodia. One of these cells of large size 
is represented in Fig. 5. 
It will here be seen to have assumed the features of an 
ameboid body. Nothing could have been more distinct 
to myself, and those who were observing with me, than
