resemble those of Scptogloeum salicinum (Pk.) Sacc. collected at the 

 same time and place. 



Septoria sambucina Pk. The form on Lonicera is probably S. Xylo- 

 stei Sacc. & Wint. Sporules 50-75 x 2/n. 



Septoria umbclliferarum Kalchb. There is no apparent reason why 

 the specimens on Cicuta and Oxypols should have been referred to 

 this species in the supplemeniary list except that I did not know what 

 to do with them and the inclusive appearance of the specific name. 

 Each host is represented by a single specimen and they do not resem- 

 ble each other. 



Uromyces euphorbiae C. & P. This includes U. proeminens (DC.) 

 Lev. on E. polygonifolia and E. Preslii and U. euphorb .icola (B. & C.) 

 Tranz. on E. maculata which are perhaps better considered as races. 



Puccinia monoica (Pk.) Arth. Dr. Arthur informs me that the Aeci- 

 dium on Arab is lyrata was collected at Trempealeau, Wis., by J. M. 

 Holzinger in 1890. 



Phyllosticta simillis-pora Ell. & Davis. What appears to be this fun- 

 gus has been described by Saccardo under the name Leptothyrium 

 tumidulum n. sp. (Ann. Myc. 10, 3, 312.) 



These notes are to be continued in a subsequent publication. 



I have followed the Sydows in Monogriphia Uredinearum in using 

 the specific name trifolii to designate the Uromyces that occurs on 

 Trifolium pratense. Kern (Phytopathology I: 1. 3 et seq.) and Arthur 

 (N. A. Flora 7: 255) apply it to the form on Trifolium repens and use 

 the specific name fallens for the rust on T. pratense. The proper dis- 

 position of the form on Trifolium hybridum is not clear. Morphologi- 

 cally it resembles the form on T. repens from which it differs in the 

 absence of an aecial stage as does that on T. pratense. Liro did not 

 succeed in transferring the rust from T. repens to T. hybridum by in- 

 oculation. 



Septoria parietariae Davis (4th suppl. list of paras, fungi of Wis. p. 

 871) is probably not different from S. urticae var. parietariae Sacc. 

 (Syll. Fung. 1(>: 971) of which T was not aware when the former name 

 was proposed. 



Peridermium balsameum Pk. has been shown by Fraser to be, in part 

 at least, the aecial stage of Uredinopsis. Fraser also finds that Caeoma 

 abietis-canadensis is connected with Melampsora on Populus grandi- 

 dentata. 



The "primary uredo" (Uredo muelleri Schroet.) occurs on the hosts 

 of Kuehneola uredinis (Lk.) Arth. (K. albida (Kuehn) Magnus) in 

 Wisconsin and might properly have been designated by the numeral 

 "I" because of its aecial character. The same may be said of 

 Phragmidium potentillae-canadensis Diet, which is placed in Kuehneola 

 by Arthur.
