March 1907] Notes from Mycological Literatvre 79 



Reed, George M. 



Under the title "Infection experiments with Erysiphe gra- 

 minis DC." Mr. Reed gives in the 15th vol. (1904) of the Trans- 

 actions of the Wisconsin Academy of Science, Arts and Letters, 

 pp. 135-162, published in 1905, a full resume of Neger's and 

 Salmon's infection work, and then proceeds to outline his own 

 experiments with this species — which (combining all reports) 

 infects fifty-five species of Grasses. Of this number only sixteen 

 belong to this country, according to Mr. Reed. We find from the 

 tables and notes given that plants on which spores were sown 

 were Triticum vulgare, Avena sativa, Hordeum vulgare, H. ju- 

 batum, Bromus mollis, Poa pratensis, P. trivialis, P. nemoralis, P. 

 compressa, Secale cereale, Lolium perenne, Festuca elatior, F. 

 heterophylla, Dactylis glomerata, Phleum pratense, Glyceria 

 fluitans.
