On Dematium pullulans de Bary. Isme A . Hoggan. 107 



III. Conclusion. 



The relationship of the fungus known as Dematium pullulans 

 to Cladosporium, Plowrightia and Fzimago having been examined, 

 it is claimed that no direct connection between them exists. 

 Reasons have been advanced for ascribing a distinct individuality 

 to Dematium pullulans. To speculate as to whether there is some 

 other perfect stage, so far undetermined, to which this fungus 

 may eventually be ascribed, is premature, and must be left, at 

 least, until the relations with Sphaerulina have been cleared up. 

 The writer would therefore be grateful for any material of this 

 fungus, or for suggestions of possible localities in which to 

 search. 



Finally, she desires to record her thanks to Mr F. T. Brooks 

 for constant supervision of the work, and for much helpful 

 advice and criticism. She is also indebted to Mr L. Ogilvie and 

 Mr A. Smith, who supplied cultures of Dematium pullulans.
