as in Clathrus. On the fourth side, the columella branches differenti- 

 ate new hyphal knots rp, which are surrounded later by receptacle 

 chamber walls and connect with the remaining lattice receptacle 

 further inwards. The parts of the receptacle in question lie directly 



along the whole length of the 

 columella branches and form the 

 thorn-like processes. 



Anthurus, leading from Colus 

 Garciae, has receptacle branches 

 which no longer anastomose at 

 the top and hence, in mature 

 specimens, surround the gleba 

 from below like the fingers of an 

 open hand. Figure 329 shows 

 this for Anthurus Sanctae-Catha- 

 rinae, which has not been studied

ontogenetically though a related form A. borealis (Aysurus borealis) 

 (Burt, 1894) has been thoroughly investigated. 



The polymorphous Aseroe, which is closely related to Anthurus, will 

 be discussed more thoroughly on account of its relationship to the next 

 family. In Aseroe arachnoidea (Penzig, 1899; E. Fischer, 1910) the 

 ground plan of the fructification is similar in principle to that of Clathrus. 

 From the columella Z. str., there proceed (Fig. 330, 1) the vertical plates 

 Z. str. zw. (branches of the columella) which later divide the gleba into a 

 corresponding number of similar vertical flabella with the alternate plates
