The twentieth century of Ellis and Everhart’s Fungi 
Columbian i, issued by E. Bartholomew, appeared Nov. 15, 1904. 
The genera represented by some four to twenty-seven species each 
are as follows: Aecidium (4 sp.), Diaporthe (4 sp.), Puccinia 
(27 sp.), and Uromyces (6 sp.). 
An undescribed Alternaria affecting the Apple is re¬ 
ported by B. O. Longyear in Science, N. S. 21: 708, May 5, 1905. 
The fungus was first found in Michigan, later in Colorado. It 
attacks the blossom end of the fruit, the affected area remaining 
small or extending over the whole fruit which then becomes 
a shrivelled dry hard mass. Inoculation experiments are being 
carried on. 
Professor T. J. Burrill gave the presidential address 
before the Buffalo meeting of the American Microscopical Socie¬ 
ty, Aug. 24, 1904, on Microorganisms of Soil and Human Wel¬ 
fare. The principal sub-heads of the lecture were Rock reducers, 
Nitrifiers, Root-tubercle Bacteria, and Nitrogen Fixation by Free 
Bacteria. 
In Novae Fungorum species — II, auctoribus H. et P. 
Sydow (Ann. Mycolog. 3: 185-6, Apr. 1905) three of the eight 
new species described are American — from Utah. These are as 
follows: Asteroma garrettianum on Primula, Ascochyta garret- 
tiana on Orthocarpus tolmiei, and Didymaria conferta on Wy- 
ethiea amplexicaulis. 
A Preliminary Report on the Hymeniales of Connec¬ 
ticut, by Edward Albert White, forms Bulletin No. 3, Connecti¬ 
cut State Geological and Natural History Survey. The annotated 
list is preceded by popular explanations of the groups and a few 
keys. The 40 plates are elegant half-tones, printed on heavy 
plate paper. 
Professor Theobald Smith gave an address on Some 
Problems in the Life History of Pathogenic Microorganisms, be¬ 
fore the International Congress of Arts and Science, St. Louis, 
Mo., Sept. 24, 1904; published in Science, N. S., 20:817-832, 
Dec. 16, 1904. He supported the hypothesis of the general phe¬ 
nomenon of infection as follows: That the tendency of all invad¬ 
ing micro-organisms in their evolution toward a more highly 
parasitic state is to act solely on the defensive while securing op¬ 
portunity for multiplication and escape to another host. 
Ernest S. Salmon’s paper On Specialization of Para¬ 
sitism in the Erysiphaceae, III. (Ann. Mycolog. 3:172-184, 
Apr. 1905) deals with Inoculation-experiments with the asco-
