shows that the species in question is different from Urophlyctis 
coproides (Trab.) P. Magn., on Beta vulgaris, and Urophylctis 
pulposa (Wall.) Schroet., on Chenopodium and Atriplex; the 
name proposed is Urophlyctis alfalfae (v. Lagerheim olim) P. 
Magnus. The galls are rounded protuberances; when sectioned 
large brown irregular figures may be seen; these correspond to 
cavities filled with the resting spores. 
The Bitter Rot of Apples is the title of Bulletin No. 77 
(Ill. Agr. Exp. Sta.), July 1902, by Thomas J. Burrill and Joseph 
C. Blair. The authors say it is essentially a hot weather disease. 
The second spore-forms were not found in exposed apples but 
the fungus ordinarily retains its vitality in a dormant state in 
the winter, and in May or later, continues its growth. It was 
also found that spores from the cankers on the limbs could be 
used successfully in inoculation experiments. This seems to be 
the first verified case to show that there is a connection between 
cankered places on the limbs and the disease on the fruit. [To 
the reviewer it would seem desirable that the scientific names of 
the fungi or forms discussed in a Bulletin should be given in 
parentheses or as foot notes.] 
Hermann von Schrenk and Perley Spaulding give a 
brief preliminary account (Science, N. S. 16:669-670, Oct. 31, 
1902) of observations and experiments showing “a causal rela¬ 
tion between apple cankers found in numerous orchards and the 
bitter rot disease, and that it is very probable that this fungus is 
capable of living both in the bark and in the fruit of the apple/’ 
In cultures made from the cankers Gloeosporium fructigenum 
appeared; the spores inoculated into living apple branches gave 
rise to apple cankers with pycnidia and spores of Gloeosporium 
fructigenum, and these spores inoculated into apple produced the 
bitter rot disease. To the reviewer this would seem a confirma¬ 
tion of results obtained by Burrill & Blair. 
Howard J. Banker gives A historical Review of the pro¬ 
posed genera of the Hydnaceae, Bull. Torr. Bot. Club, 29: 436- 
448, July 1902; he proposes Tylodon based on T. friesii (Radu- 
lum pendulum Fr. El. Fung. 149) and Etheirodon based on E. 
fimbriatum (Odontia fimbriata Fr) as generic names to replace 
respectively Radulum and Odontia. In the summary 71 generic 
names are enumerated; of these 32 are free to be used. 
An extended article on the toxic properties of some 
copper compounds, by Judson F. Clark, is published in the Jan. 
No. of the Botaincal Gazette (33: 26-48 1902). Several hundred 
cultures with fifteen species of Fungi were made and fully de¬ 
scribed. He says that all experiments go to show that the Bor¬ 
deaux Mixture is effective from the day it is applied. As to 
its toxicology: “The solution of that part of the Cu (OH)2 of
