instances, the stem probably remains rudimentary until the 

 spores are matured, when it elongates for the purpose of raising 

 the peridium to the surface, thereby facilitating the dispersion 

 of the spores." ^ 



The subterranean Gastromycetes, which technically belong 

 here, are treated in the chapter on subterranean Fungi, because 

 of their similarity in habit and appearance ; but for all this 

 they must not be confounded, and cannot be if the fructification 

 is properly remembered.
