tramal plate is formed in these angles and (in the intermediate tissue) the 

 receptacle chambers; in contrast to C. cancellatus (Fig. 319), however, 

 the tramal plates are not irregularly arranged but grow up on the inmost, 



oldest receptacle chambers and surround them on 

 three sides, (Fig. 323, 4, Rpi) whereby they inter- 

 twine closely with the pseudoparenchyma of the 

 chamber wall. The receptacle chambers Rp 2 , 

 which later are formed further out, do not come 

 into contact with the first receptacle chamber 

 Rpi. They do not come into close contact with 

 the tramal plates, however, but remain separated 

 from them by a layer of gelatinous hyphae. 

 Therefore, the gleba in the mature expanded 

 receptacle does not hang as a whole (as in C. 

 cancellatus) from the interior of the receptacle 

 branches but only in small portions, surrounded 

 by the torn Rd in the corners of the nets in 

 small knobs, the original receptacle chambers 

 Rpi (Fig. 324). It is further characteristic of 

 Clathrella, that at its base the latticed branches fuse to a tube. The 

 receptacle, thus, no longer rises in these lower parts, corresponding to 

 the splits in the branches of the columella, in the form of single columns 

 but as a hollow cylinder around the columella.
