Mycologia 
The temporary suspension of vitality in the fruit-bodies of cer- 
tain hymenomycetes has been recently studied by A. H. R. Buller 
and A. T. Cameron, who conclude that dried fruit-bodies of Dae- 
dalea unicolor exposed in darkness to air at room temperatures 
are able to retain their vitality for at least seven years, and those 
of Schizopliylhim alneum will remain alive under similar circum- 
stances for nearly six years. 
In the Journal of Agricultural Research for May, 1914, James 
R. Weir describes Fomes putearius and Trametes setosus as new 
wood-destroying fungi in the forests of the Northwest. The 
former is said to be closely related to Pyropolyporus conchatus, 
but always occurs on coniferous wood, with a preference for the 
larch ; while the latter, occurring chiefly on Pinus monticola, 
seems to be most closely related to Hapalopilus gilvus. 
Paul W. Graff reports several additions to the basidiomycetous 
flora of the Philippines in the Philippine Journal of Science for 
November, 1913, among them Exidia lagunensis. Laschia philippi- 
nensis, Lentinus candidus, Lentinus lagunensis, V olvaria pruinosa, 
Naucoria malinensis, and Bovista Jonesii, described by him as 
new. From a study of fresh specimens of Hcxagona luzonensis 
Murrill, he concludes that this species belongs in the genus 
Laschia and transfers it to that genus. 
In the Annals of the Missouri Botanical Garden for March, 
1914, a paper appeared by Mr. L. O. Overholts on the Polypora- 
ceae of Ohio, which listed about 100 species found within the 
state, of which 78 were collected by Mr. Overholts. Duplicates 
of most of these species were sent to the New York Botanical 
Garden for determination and verification and are now in the 
Garden herbarium. The paper contains descriptions of all the 
species listed, together with notes on their occurrence, hosts, and 
distinguishing characters. With the aid of this paper, students 
should find little or no difficulty in recognizing practically all of 
the pileate polypores of Ohio.
