A species of rather common occurrence and of wide distribu- 

 tion. Numerous cultures have clearly established the life his- 

 tory. The urediniospores have the same pore arrangement as 

 those of Puc. asterum but the spores are larger. The telia are 

 characterized by being unusually broad for their length, they are 

 oval or even roundish, whereas most sedge rusts have oblong or 

 linear telial sori. On Carex trichocarpa the sori of this specfes 

 are frequently intermingled with those of Puc. Sambuci. The 

 small roundish sori of Puc. Peckii are usually easily distinguished 

 from the robust elongated sori of Puc. Sambuci, even without 

 microscopic characters which would make separation certain.
