narrower in the middle, ends rounded, conspicuously 2-4 guttu- 

 late, 6-12x3/x. The appearance of the sporules suggests that 

 later they may become septate. 



Phyllosticta cruenta (Fr.) Kickx. The reference of this species 

 to Macrophoma as proposed by Ferraris (Ann. My col. 10:3:288 

 (Jn. 1912)) would make a generic distinction between the two 

 forms that were given as varieties in the provisional list because 

 the globose sporules of Ph. pallidior Pk. are only about 10* in 

 length, although they equal in content the longer and narrower 

 sporules of the type of Ph. discincta. 



Ascochyta pisi Lib. has been shown by R. E. Stone to be a con- 

 idial form of Mycosphaerella pinodes (Berk. & Blox.) Niessl 

 (Ann. Mycol. 10:564: et seq. (Dec. 1912). Also R. E. Vaughan, 

 Phytopathology 3:71 [1913]. 



Actinonema rosae, (Lib.) Fr. Uiedicke calls this Marssonina 

 rosae (Lib.) Trail (Ann. Mycol. itf:146 (Apr. 1912) ). F. A. 

 Wolf has developed the ascosporous stage which he refers to the 

 Microthyriaceae and makes the type of a new genus and calls it 

 Diplocarpon rosae F. A. Wolf. (Bot. Gaz. 54, 231 (Sept. 1912) ). 



Septoria nubilosa Ell. & Evht. (Proc. Acad. Nat. Sci. Phil. 

 1891, p. 76) which was founded on Wisconsin material on Hele- 

 nium autumnale has not been included in the Wisconsin lists be- 

 cause it is merely a form of Septoria helenii Ell. & Evht. in 

 which the spots are not well developed. The type was collected 

 on the north side of plants bearing typical S. helenii and was 

 sent to the authors merely to show the variation. 



Septoria ribis Desm. Some of the specimens that I have re- 

 ferred to this species are perhaps S. grossulariae var. longispora 

 Ferraris (Ann. Mycol. 10:291). Typical S. grossulariae (Lib.) 

 West. I have collected but once. 



Septoria saccharina Ell. & Evht. Specimens from Price Co. 

 bear sporules about 30x2i/ 2 ^- The Acer— inhabiting fungi, 

 having triseptate sporules borne in acervuli and varying 

 in length from 20-70/x and in width from iy 2 -5/i seem to me to 

 constitute a group the relation of the members of 'which can 

 be determined by inoculation methods only. The form with short 

 and thick sporules has been called Ascochyta aceris Lib. and later
