GENERA HYPOCRELLA AND ASCHERSONIA. 



535 



far as regards the Hypocrella stage, but in practice it is found 

 that, in this group, the Hypocrella and Aschersonia stages 

 frequently occur in the same stroma. Eu-aschersonia and 

 Eu-hypocrella are used below for the two stages of the Aleu- 

 rodiicolous species. 



The species may then be arranged as follows ; in a number 

 of cases the Aschersonia stage is known, but has not been given 

 a separate name : —

When only a small amount of material is available, it 

 appears possible to spUt these species into well-defined groups, 

 characterized by their form, but as specimens accumulate it 

 is found that the forms grade into one another to such an
