Bulletin No. 44, Bureau of Plant Industry, U. S. De¬ 
partment of Agriculture, (issued July 18, 1903) is devoted to the 
subject of Bitter Rot of Apples, the authors being Hermann von 
Schrenk and Perley Spaulding. It is illustrated with twelve 
plates. It is an exhaustive treatise giving an historical account, 
distribution, description of the rot, the bitter-rot fungus, the 
canker stage, remedial measures, and index to literature. The 
Bitter Rot (or Ripe Rot) of Apples was, according to Curtis’s 
catalogue, in the United States before 1867, but it was not until 
1874 that the fungus was described by Berkeley. Names in com¬ 
mon use as Gloeosporium fructigenum, Gl. rufomaculans, and 
Gnomoniopsis fructigena, have been relegated to synonomy by 
the use of a new generic name, Glomerella, proposed by the 
authors — not however published here for the first time as might 
be supposed: see Science, N. S. 17:751. 8 May 1903. 
A Notice of Work Done on the White Rot of the 
Grape (Coniothyrium diplodiella) by Gy. de Istvanffi is given 
in the Botanical Gazette (p. 147-8, Aug. 1903), being a review 
of that author’s Etudes sur le rot livicle de la vigne, published 
by the Hungarian Minister of Agriculture in 1902. A minute 
description of the development of the disease is given, including 
the reactions induced in the host plant by the fungus. The most 
interesting part is that which deals with the effects of various 
toxic substances on the fungus.
