specific name first given to the perfect stage (veneta). Adopting the 

 first name applied to the perfect stage seems to be the general rule 

 among European mycologists. In America, however, there are 

 many who believe that the first name given to any stage should be 

 the one used. If the latter rule is adopted, then the name veneta 

 cannot hold. The first name given to any stage was Fusarkim 

 platani Mont., and hence the fungus would have to be called Gno- 

 monia platani (Mont.). This will only be settled, however, when 

 botanists come to some conclusion as to the nomenclature of poly- 

 morphic fungi. Also if w^e wish to be consistent in our use of names 

 of the imperfect stage, we should use Gloeosporium platani instead of 

 G. nerviscquum. However, it is of little importance what the imperfect 

 stage is called, it is at best only a synonym. 



The synonymy of this fungus as given by Klebahn includes six- 

 teen names. To this may be added the following : Gloeosporium cana- 

 dense E. &E. Jour. Myc. 5: 153; Myxosporium platanicolum E. & E. 

 Proc. Acad. Philad. 1894:572 (distributed in N. Am. Fungi as

Pseudopeziza type 



The genus Pseudopeziza was first connected with a Gloeosporium 

 by Klebahn (26) in 1 905 , who found the perfect stage of G. rihis, a 

 form common on currant leaves, to be P. rihis Klebahn. He developed 

 the perfect stage by putting the leaves out of doors in a protected 

 place to winter; and in the spring he found it in abundance. 



My investigation of this form has been very limited. Only a

form in pure culture. An attempt was made 



to produce the perfect stage, but it was without success.
