Clinton (Rep. Conn. Agr. ‘Exp. Sta. I909-IQIO: 719. I9QI1) 
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 Jsuga, resulting in the development 
of the typical uredinia of this species. 
Fraser 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 Peckti, 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.
