In Europe and North America the aecidia occur on Abies pectinata DC. 
The uredo stage has been described from New Zealand material, but the 
aecidia and teleuto stages have been described from material kindly supplied 
by Dr. J. R. Weir (herb. J. R. Weir, No. 11555) and Mrs. F. W. Patterson 
(U.S. Dept. Agr. Myc. Exc., Nos. 744, 745). 
The uredosori are small and — overlooked, largely on account of 
their being immersed in the host-tissues; their presence is, as a rule, 
indicated by the presence of small bud areas on the leaf.
