Clinton (Rep. Conn. Agr. Exp. Sta. 1909-1910: 719. 1911) 

 was the first to show that the aecial stage of this species occurred on 

 Tsuga canadensis. He successfully infected Gaylussacia baccata by 

 sowing with aeciospores from Tsuga, resulting in the development 

 of the typical uredinia of this species. 



Eraser in 1912 (Mycol. 5: 237. 1913) confirmed Clinton's work 

 by obtaining the development of aecia on the leaves of Tsuga canadensis 

 following sowings from teliosporic material on Vaccinium canadense. 

 The same author in 1913 (Mycol. 6: 27. 1914) obtained aecia on 

 Tsuga canadensis following sowing of teliosporic material from Gay- 

 lussacia resinosa. The aecia developed in these experiments are 

 similar to those of Peridermium Peckii, but may represent an unde- 

 scribed form. 



No aecia collected in the west have been referred to this species 

 though they doubtless occur on Abies or Tsuga heterophylla.
