In nearly all cases those host plants which were badly affected 

 grew in or on the large nests in a sphagnum swamp built up by a 

 species of black ant, and which seems to have affected the vigor of 

 the plants growing on these ant nests. The same host, A^ a 1 e r i a n a 

 uliginosa, exhibits a rust, Puccinia comutata. 

 new to the eastern United States, and other species of plants grow- 

 ing on the ant nests were variously diseased.
