This formation of a basal tube leads from Clathrella to a series of 

 other genera whose receptacle extends into a longer or shorter stipe, as 

 Simblum (Fig. 325) and Colus (Fig. 326). Both may be considered as 

 stipitate Clathrus or Clathrella forms, but with the gleba confined to the 

 apical portion of the receptacle (Conard, 1913). 



In contrast to these forms is the Chinese Lysurus Mokusin, where 

 the distal parts of the branches of the columella, not the proximal, show 

 intercalary growth (Fig. 327, D). The receptacle fundament Rp remains 



lying in the curve of the branches of the 

 columella pi and the originally narrow cavities 

 Gl. Km. do not arise, as in Clathrus (Fig. 319), 

 between Rp and HA, but on both the exterior, 

 distal sides of Rp. As the receptacle lies 

 directly on the columella, there is no space 

 there for the development of the tramal plates ; 

 these grow rather from sides of the branches 

 of the columella PI into the free space outside 

 the receptacle, so that the gleba finally lies 

 between the receptacle Rp and the volva gel 

 plates G, and consequently clings to the un-

 side of the receptacle branches. 



A development probably similar to that of Lysurus, is that of the 

 South African Kalchbrennera corallocephala (K. Tuckii) whose ontogeny 

 is incompletely known (Fig. 328). A pallid stipe, cylindrical or thicker 

 toward the top, rises from the volva. At the clavate tip, the stipe wall 

 disappears into a narrow-meshed lattice whose ribs (the continuation of 

 the stipe wall) are colored an intense cinnabar red and are a cross- 

 wrinkled above. Up to this point the receptacle corresponds to that of
