which are a little longer than broad; up to twice as long. When the cystocarps 

 are ripe, the cushion is thicl^er, the hlaments somewhat longer, the constituting 

 cells more numerous and sometimes longer. The carpogonia are terminal on parti- 

 cular (3 — )4 — 5-celled branches given olT from one of the undermost cells in a 

 nemathecial filament or from one of the bottom cells of the nemalhecium (fig. 116). 

 As in the foregoing species, the carpogonium encloses one side of the subterminal

cell, giving off a production reaching beyond the under face of this cell. In some 

 cases no such lateral production was found, but these carpogonia were doubtless 

 abnormally developed, abortive (fig. 116 C*). The auxiliary-cell branches which are 

 given off from the lowest part of the nemathecial filaments consist of about four 

 low seemingly equal cells. In fig. 116 £ two fertilized carpogonia are shown, from 

 which sporogenous filaments growing in a horizontal direction are given off. A 

 similar filament in connection with an auxiliary-cell filament is shown in fig. 116 D. 

 The development of the cystocarp lias not been followed. At maturity the cysto- 

 carpial nematheciuin contains numerous rows of carpospores, each row consisting 

 of up to five almost globular carpospores, each surrounded by a thick hyaline wall.
