STRUCTURE OF AGARICS, PARTICULARLY OF THE 

 HYMENIUM. 



By J. De Seynes.* 



When first studying the Hymenomycetes one easily perceives that 

 there are no precise rules nor definite characters for their classifica- 

 tion. The limitation of the species among Phanerogams has already 

 been subjected to much controversy, but in this respect the Fungi 

 are far surpassed by the more fortunate vegetables, the fruits and 

 flowers of which can be submitted to rigorous analysis. Here the 

 characters are founded upon organs of such a nature as to neces 

 Bitate the employment of the microscope, and a simple cell corres- 

 ponds with many more complicated organs among the superior 

 vegetables. The form of this cell ought to have its importance, 

 above all the study of the fruit in one of large size, although it 

 may be reduced to a simple cell ; this cell offering differences of 

 form, colour, &c, sufficient to furnish good characters. One ought 

 not, therefore, to separate the anatomic study of the types from 

 that of their external characters, which are visible to the naked 

 eye. Whilst we are searching in this way for a fit union between 

 the two, an important work is being published in Germany with
