Farmers' Bulletin 789 of the U. S. Department of Agriculture 

 treats of certain insects that attack mushrooms and the means of 

 controlling them. The chief insects considered are maggots, 

 mites, springtails, and sowbugs, the first class being the most im-

 screened ; if the spawn is purchased from reliable dealers ; and if 

 the compost is carefully prepared and kept at as low a tempera- 

 ture as possible, there should be little necessity for the radical 

 measures of fumigation, sterilization, or destruction of the mush- 

 room beds.

Three new polypores have just been published by W. H. Long 

 in the first number of the Papers of the New Mexico Chapter Phi 

 Kappa Phi. Polyporus pseudo sulphur eus was collected on live 

 oak near Ocala, Florida, as well as from three other localities in 

 Florida on the same host. Fomes arctostaphyli, which is said to 

 be the smallest species of this genus with brown context yet re- 

 ported from North America, was collected abundantly on Arcto- 

 staphylos at various places in Arizona. The author says it is very
