use rujomaculans until some one develops the perfect stage from 

 some other host, the conidial stage of which was described before 

 rujomaculans; and this older name would stand until another earlier 

 one was found. Our names would be in an unstable condition until 

 the perfect stage was developed from the first described Gloeosporium. 

 Furthermore, if we consider the forms from different hosts distinct 

 enough to be species, and also use the name first applied to the perfect 

 stage, the name Glomei " ' 

 the form from apple. 



While the various forms are morphologically very similar, some of 

 them at least seem to be quite well separated from the rest. While 

 the reactions to culture media are not very trustworthy, we can get 

 some idea as to the relationship of the form's. There are some forms 

 which do seem to be very closely related and very Hkely are the same; 

 the forms from Dracaena, Funs elaslkd, Anthurium, Coffea, and 

 Sarracenia seem to be very close together and should be considered 

 identical. Whether these are identical with the fungus causing the 

 bitter rot of apples is somewhat questionable, though they are very 

 close to it. There are some differences between them, as, for instance, 

 the size of the germ tube in the germinating coridium, which is much 

 larger m the apple form (figs. 30, 36, 38, jp). The forms on Sarra- 

 cenia and Anthurium seem to be undc^cribed. The anthracnose, 

 however, has not been found on the Sarracenia plants in the bogs, 

 though It has been looked for. Species of both Gloeosporium and 

 Collctotnchum have teen described on the coffee tree. Of course it 

 IS impossible to identify the one studied here positively with any of 

 them but so far as the descriptions go it would fit either. 



The form from cotton seems to be quite divergent from the other 

 torms, and doubtless should be considered a distinct species. The 

 cultural characters are quite distinct and it takes but poorly on apple. 

 Also on Elfvmg's nutrient solution the myceHum breaks up into large 

 ceus {fig. 34) ,vhich are capable of growing into mycelium again, a 

 character which has not been found in other forms. I was not able 

 to bung the perithecia to maturity, that is, the asci did not develop
