FlG. 21. - There may lie seen stilj in Ihc preparations ;i. great deal of very small 

 thready pieces, some of llicni containing l\vo or three cells. Bigger ones, (if a. round or 

 lengthened shape, contain one or more vaciioles, which were believed to lie Chlamy- 

 dospores. 



Kin. 22. - - r.ertain spherical slriunas on .small branches ai'c the pseudocoiiidcu 

 which seemed to he similar to those of the Morticrellu. Perhaps ought we to consider 

 them as small bulbs and as playing a part in the reproducing processes? 



FIG. 22 X . - These strumas are somelinies prolonged by a filament. 



When treating the white Mycelium of tniflle by means of a strongly diluted solution 

 of hyperchlorite and when leaving it long enough exposed to its action, one succeeds 

 in perceiving its structure without destroying the general sight of the fungus. 



We may see then that the main filament is formed by several sections, which, put 

 together, constitute its whole length. The number of cells comprised within the thickness 

 of the filament, varies according to said thickness and the tissue, first well developped 

 goes down, towards the ends, to a singular range of cells. 



FIG. 23. At the ends of the filament the latter is sometimes composed of a parti- 

 cular kind of tissue; said tissue, a very rudimentary one, being only constituted by 

 groups of few cells, separate from eachother and situate, at a regular distance from 

 eachother, in the mycelious tube and a strange feature is that said tube is not quite 

 closed by said tissue on the points where it developped itself.
