Upon fertilization taking place, which is as in Nemalion, 

 the peripheral cells of the carpogonium (excepting those con- 

 stituting the trichophore i.e., the trichogyne-bearer) undergo 

 division, and become developed into articulated branches, 

 which lie side by side, and form a more or less spherical

 tral cell' of the carpogonium develops processes or outgrowths 

 which eventually become spores, occupying the cavity of the 

 "pericarp" (A, s, Fig. 185). An interesting fact in this 

 connection is that neither the trichogyne nor trichophore 

 take part in the development subsequent to fertilization ; in 

 other words, the cells which directly receive the influence of 

 the spermatozoids do not themselves undergo a subsequent 

 development, but adjoining ones do develop, on the one 

 hand, into the spores, and on the other into the filaments 

 of the pericarp. The sporocarp in this genus is thus seen 

 to be somewhat more complex than in Nemalion, including
