very great difference in the type of alternation of generations 
point to the conclusion that the evident similarities between the 
two groups are rather to be regarded as analogous developments. 
Unless the case can be made much more evident than at present, 
even the more or less superficial similarity between the structures 
of the ascocarp and cystocarp cannot be urged as very strong 
evidence in favor of a direct origin from the Rhodophyta. 
Whether all the fungi containing an ascus shotild be placed 
in a single class and whether the Teliosporeae should be retained 
in a class distinct from the Basidiomycetae are questions which 
depend on one’s definition or conception of a class. It is very 
desirable to have a system that is fairly consistent for the entire 
plant kingdom, if botany is to be a science and not simply a group 
of disjointed subjects.
