FIG. 14'. -- When perceiving in a preparation said ,end branches, so very thin, near 

 tin- main filament, the difference of thickness makes one believe them to be 2 quite 

 different fungi, one of them being partitionned, the other not. 



The main filament measures from 2 y. to 4 y. ; the end branches measure from 1/3 ft 

 to 2 P. 



FIG. 15. Said ramifications, being bereft of liquid in one part of their length, get 

 Hal and distorted, their cells showing here their face, there their side. 



FIG. 16 & 17. - - Here and there are tearings in the membrane through which the 

 contents of the cells were spilled.

In order to detect the structure of the filament it is necessary, first to discharge it 

 from the liquid therein contained, then to colour it. 



If the used solution of chlorinated soda is too strong, the membrane will be destroyed 

 on several points, the filament will go into pieces and in the preparation will only 

 remains more or less short pieces of it, but which, nevertheless, will allow everybody to 

 get an idea of its microscopical structure. 



FIG. 18, 18 & 18'. - The main filament is not a mycelial tube, closed up, from 

 distance to distance, by crossing rectilinear partitions as there are in most of the fungi; 

 it shows, in the contrary, a special structure. 



In fact, it is formed by a fasciculus of polyedrical cells, clustering together in an 

 irregular way and constituting a real cellular tissue, so that its term of a filament 

 is a wrong one. 



The cells are filling up entirely the whole thickness of the filament, leaving no free 

 space therein. They are so small that at the first look they are taken for granulations of 

 the membrane; some of them are of a greater size and constitute the vacuoles. In fact, 

 they are containing the many oildrops which the filament shows on the whole of its 

 length. 



FIG. 19. - - The structure of the filament is not a uniform one in its whole length; 

 I lie number and the position of the cells varying according to the point where they are 

 situated. 



FIG. 19\ Sometimes, between two points where the cellular tissue is well deve- 

 lopped, the filament consists only of a single range of cells. 



FIG. 11) & 19". - - The tissue is slowly getting simplified towards the ends of the 

 lilament, where the latter shows thus the real thready structure.
