porated within the body of the former. Moreover to do this 

 would necessitate making an entire recast of the article which 

 for several reasons is impracticable and would lead to still 

 farther delay in publication. Therefore, it seemed best to 

 include this report in the form of the following tables, along 

 with certain explanatory matter and comments, as an appendix 

 to the original paper. 



Attention is called to the fact that Dr. Wollenweber has deter- 

 mined the species without knowing the results of Dr. Lewis' 

 studies on their pathogenicity. Only a list of the hosts from 

 which the species were isolated was furnished when the original 

 pure cultures were delivered to him for determination. As will 

 be seen in the discussion following the table most of the species 

 are already described or have been mentioned in the literature 

 upon the subject. In case complete descriptions are lacking he 

 will include them in his monograph or some other publication 

 in the near future. He has very kindly consented to this pre- 

 liminary publication of the names previous to the final and more 

 complete description. However characters considered to be 

 important for the differentiation of new forms and new combi- 

 nations have been furnished by him and are briefly discussed in 

 the following pages. 



List of Species of Fusarium as Determined by Dr. WonENwEBER-t

F II 1 172 F. helianthi Sacc. (s. var.) " " 



F III 1 173 F. pirinum " " 



F IV 1254 F. helianthi " "

t In the above list the Roman numerals preceded by the letter F 

 designate the names under which the different strains or cultures of 

 Fusarium are carried in this laboratory. The second and third columns 

 give Dr. Wollenweber's serial, laboratory number and his -determina- 

 tion of all the cultures sent him, with two exceptions, F X and F XL 

 The last column gives the source from which each culture was obtained. 

 Those marked (*) were not sent to him. Attention is called to the fact 

 that F XII, F XV (including F XVI), and F XVIII, received by and 

 carried in this laboratory as F. putrefaciens Osterwalder, F. oxysporum 

 Smith and Swingle, and F. roseum Lk. and referred to by these names 

 throughout his paper by Dr. Lewis are designated as F. pirinum (Fries) 

 Sacc, F. orthoceras App. and Wr., and F. reticulatum Mont, by Dr. 

 Wollenweber.
