NOTES AND BRIEF ARTICLES 



Professor W. T. Home, of the State University of California, 

 spent about six weeks at the Garden this summer after his return 

 from Cuba, investigating the cytology and morphology of Ar mil- 

 iaria mellea. 



In an article in Phytopathology for February, A. S. Rhoads 

 gives new hosts for a number of our common wood-destroying 

 fungi and urges collectors to use more care in determining and 

 listing the hosts of this class of fungi. 



Sandy sporophores of Fomes pinicola are described and 

 figured by A. A. Hansen in Torreya for April. The sporophores 

 grew on an old log of Finns resinosa found on the shore of Lake 

 Superior. 



D. C. Babcock, in a bulletin of the Ohio Experiment Station, 

 gives popular descriptions and suggestions for control of a 

 number of common diseases of forest and shade trees found in 

 Ohio. 



It is said that rose leaf-blotch, caused by Actinonema Rosae, 

 may be prevented by repeated spraying with lime-sulphur solu- 

 tion, beginning before the buds open in the spring and repeating 

 at intervals of ten days throughout the growing season, except 

 when the roses are in bloom. 



The gladiolus is subject to a hard-rot disease due to Septoria 

 Gladioli, which affects both the leaves and the conns. Crop rota- 

 tion and the burning of affected leaves in the autumn are sug- 

 gested by L. M. Massey as means of partial control.
