The aecia on the above named hosts resemble very closely the Aeeid- 

 ium on Oxygrapliis Cymhalaria (Pursh) Prantl. which belongs with Puc- 

 cinia cinerca Arth. on Pou. and may be shown by cultures to belong with 

 it. This is especially likely since its range practically coincides with that 

 of this Puccinia.
