glabellus? "Elkhorn, Montana. September 10, 1889. The 

 fungus was rather immature, growing on a high mountain 

 peak, on a host too far gone for sure identification of species, 

 but which looked like a dry season mountain form of Erigeron 

 glabellus. (7) On Hclianthus annuus L.. Helena. Septem- 

 ber 2, 1889. The fungus covered the host en both leaf sur- 

 faces. The host grew on a damp spot along a railroad.

 fungus. Collected September 2, 1889. (9) On Aster sp., 

 Bozeman, June 20, 1889, by Mrs. M. L. Alderson. Re- 

 markable for its exceedingly early date. (10) On Verbena

host very materially. 



Erysxphe graminis DC. Of this fungus there are two 

 specimens in my herbarium, both obtained by Mr. Anderson 



in Northern Montana, one upon Poa tenuifoha Nutt., band 

 Coulee, July, 1888; and the other upon Agropyrum glaucum 

 R. & S.; leg. F. W. Anderson, Great Falls, August. 1888. 



Uncinula Salicis (DC) Winter. On Salix .fa™ccns 

 Nutt., September, 1888. Exceedingly abundant in 1888, but 

 very scarce in 1889, possibly because of the extreme dryness
