An article recently published by Mr. L. O. Overholts in the 
Annals of the Missouri Botanical Garden contains descriptions 
and illustrations of four new species of gill-fungi : Claudopus 
subnidulans, Panaeolus reticulatus, P. rtifus, and P. variabilis. 
. All of the species were collected by Mr. Overholts in the vicinity 
of St. Louis, Missouri. 
Volume 6 of the Memoirs of the New York Botanical Garden 
contains thirty-seven papers presented at the celebration of the 
twentieth anniversary, among them “ The development of Lepiota 
cristata and L. seminuda,” by G. F. Atkinson, “ Japanese species 
of Gyninosporangium,” by F. D. Kern, “ Chemotropic reactions 
in Rhizopiis nigricans,” by A. H. Graves, and “ Bermuda fungi,” 
by F. J. Seaver. 
Dr. S. M. Stocker, of Duluth, Minnesota, contributes the fol- 
lowing note: “On September 7, 1916, I found a specimen of 
Pluteus cervintis so much larger than any heretofore seen by me 
that I measured it. The outline of the cap was oval, not circular, 
and the measurements were 93^ X 7 inches. Perhaps this is not 
unknown, but it seems to me worth letting you know.” 
A fine fresh specimen of Thelephora vialis has been sent in for 
determination by Mr. Timothy E. Wilcox, of Washington, D. C. 
It is large, many times lobed, rosy-smoke-colored below and 
cream-colored to honey-yellow above, with a somewhat disagree- 
able odor in drying which is very noticeable. Dr. Burt reports 
a former collection of this species at Washington by ]\Ir. F. J. 
Braendle. 
The July number of the Journal of Agricultural Research con- 
tains an article on the disease of potatoes known as “ leak,” by 
Lon A. Hawkins. The disease usually appears after the crop 
has been harvested and according to Hawkins is caused by the 
fungus Pythiurn debaryanum Hesse. Rhiso pus nigricans Khrcnh.
