sweet potatoes. He finds that drying the potatoes quite thor- 
oughly before storing them largely prevents decay. 
Mr. Edward T. Harper continues his report on species of Pho- 
liota in the region of the Great Lakes, in the Transactions of the 
Wisconsin Academy of Sciences for 1913. The plates used in 
illustration are not less handsome and attractive than in former 
papers. A number of species of Stropharia are also included in 
this report. 
Mr. Simon Davis, in a recent number of Rhodora, gives an ac- 
count of a large number of interesting gill-fungi collected by him 
at Stow, Massachusetts. Many of the species are rare and local. 
Mr. Davis intends now to turn his attention particularly to the 
genus Inocybe, and he will be glad to receive specimens for the 
study of this genus from any source. 
The genus “Muciporus” is discussed by H. O. Juel in a recent 
number of the Arkiv for Botanik, the discussion closing with a 
list of the known species of the Tulasnellaceae, including Gloeo- 
tulasnella and Tnlasnella. In a plate showing microscopic studies 
of Poly porous corticola Fries, Tnlasnella thelephorea is shown to 
be the original of Muciporus corticola. 
Miss Elsie M. Prior, in the Journal of Economic Biology for, 
1913, gives an account of her studies on the fungous disease of 
beech trees known as the “ snap-beech ” disease, which causes the 
trunk to break fifteen to twenty feet above ground. This disease 
is attributed to Bjerkandera adust a, which enters the tree by 
wounds and destroys the wood through the activity of enzyms. 
Successful artificial cultures of Clitocybe illudens and Armil- 
laria mellea on beef-malt-agar medium have been made by V. H. 
Young of the University of Wisconsin, who gives a brief descrip- 
tion of his cultures in the Botanical Gasette for June, 1914. The 
fruit-bodies obtained in the first generation proved to be quite 
normal, but those in the second spore generation showed striking 
variations in form.
