vn, No. 2, Washington, Mar. 10, 1892, pp. 103-104. 
The disease is caused by Spongospora solani Brunch., and was noticed in potatoes pur¬ 
chased in Quito, Ecuador. Describes minute characters of the fungus and gives a short 
synonymy of the species, concluding it should be known as Spongospora mbterranea (Wallr.).

Notes that spores of fungus do not penetrate the plant, but, falling to the ground, aro 
carried to tubers by the rain and cause rot. Spores seldom penetrate the ground more than 
4 inches, and hilling up the vines as early as possible in the season is recommended as a pre¬ 
ventive of rot. (J. F. J.)

In 1888 the author’s attention was called to a serious disease of grains in South Ussnria, 
and in 1889 lie received specimens from Wladvwostok. together with drawings and descrip¬ 
tions of the fungi oocuring thereon made by N. Paltscliewsky and N. Epoff. Gives a short 
review of tlie literature of similar diseases of grains, stating that the appearance of “in¬ 
toxicating grain” is no new phenomenon, it having been previously reported from Germany 
and Sweden. The diseased grain, when eaten, produces in men a serious disease; the prin¬ 
cipal symptoms being pain in ihe head, vertigo, nausea, loss of sight, etc. In South Ussnria 
besides rye, wheat, oats, millet, etc., were diseased, and not only men, but also animals
