Willi regard to this whole situation it may be said that the suggestion 

 made by Dr. Peck ('81)' should have prevented any such confusions. He 

 states that Diplodla and Spliacropsls are merely form genera, and that 

 l)oth fail in their chief distinction. Accordingly the oldest generic name 

 should be selected for species like this one, where spores are such that it 

 may be classed either as Sphiicropsts or Diplodiw, and further the sep- 

 aration of the two genera on the basis of the presence or absence of a 

 septum in the spoi*es seems little warranted. It seems that Saccardo was 

 fittie justified in changing the name Sphacropsis malonim Berk, to Phoma 

 inaJoniin (Berk.) Sacc, for it is quite possible that Berkeley described 

 an immature organism. It is cpiite connnon to find spores gi'eenish in 

 black rot of apples. After maturing tliey are brownish. 



The discussion of such a situation in regard to the name of a fungus 

 may seem somewhat unimiiortant, yet it serves as a good example of 

 some of the lack of thorough investigation and the mere guessing at de- 

 tails, which lead to just such confusion. As yet the writer is not wholly 

 satisfied with any of the names. The types of several species will have 

 to be carefully compared before any name can be accepted. 



In concluding this phase of the subject there are listed a number of 

 species with citations to literature, which it seems to the writer must be 

 considered in determining the cori'ect name of this fungus, and which 

 names should appear in synonomy.
