The central capsule, enclosed in the fenestrated shell, exhibits in its 

 lower half four large club-shaped lobes, each of which includes in its 

 upper part a large oil-globule. The uppermost, undivided part of the 

 capsule includes the nucleus, which protrudes four small nuclear lobes 

 through the four holes of the cortinar septum into the thorax. 

 Numerous long pseudopodia arise from the granular sarcomatrix, 

 which the capsule surrounds, and pass through the pores of the 

 siliceous shell.
