The leading idea of the present gronp is the complete 

 differentiation of the peridiola, which were mistaken by the 

 early mycolt^jsts for the reproductive bodies. In Poly- 

 saeeum the peridiola are present, but not so completely free, 

 owing to the persistence to some extent of the txamal 

 plates. 



CYATHTS. Haller. (fig. 6, p. 20, and fig. 7, p. 28.; 



Peridium consisting of three layers, apex at first closed by 

 a membrane (epiphragm), becoming broadly open ; peridiola 

 compressed, nmbilicate, attached to peridium by an elastic 

 cord (fnniculus).
