is autoecious. Teliospores from C. sepium were sown in the greenhouse 

 on the same host with subsequent abundant development of pycnia and 

 aecia.

 This is a micro-Puccinia correlated with Puccinia inicroica Ellis 

 which is an opsis form. The latter was originally reported as occurring 

 on Sanicula sp., which was an error for Deringia canadensis.

 Arthur in Jour. Myc. 10:18. 1904, shows by culture that Aecidium 

 Ranunculi Schw. has its telial stage on Sphenopholis pallens (Eatonia 

 pennsylvanica (DC.) A. Gray), having obtained infection on E. penn- 

 sylvanica resulting in uredinia by inoculation with aeciospores from 

 Raminctdus abortivus. Field observations made by the writer in con- 

 nection with the collections listed above lend confirming evidence to the 

 cultural results by Dr. Arthur. On May 1 the writer collected Aecidium 

 Ranunculi Schw. (2238). Almost in contact were found the leaves of 

 grass at that time not yet fruiting, bearing fresh uredinia (2237). The
