The new genus Leptoderma, which is distinguished from Lam.- 

 proderma by the thickened sporangium wall and occasional presence 

 there of deposits of carbonate of lime, is described, with one spe- 

 cies L. iridescens; also two other new species, namely, Diderma 

 arhoreum, and Diachaea cerifera. A. D. Cotton. 



Baker, S. M., Note on a New Treatment for Silver-Leaf 

 Disease in Plum Trees. (Ann. Bot. XXVII. p. 172. Jan. 1913.) 



The writef suggests the possibility of using the mycelium 

 destroying enzyme in the fruit bodies of Coprinus as a remedy for 

 the disease known as Silver-Leaf. The treatment consists in hypo- 

 dermic injections of a concentrated water extract of the deliquescing 

 sporophores, and also in external applications at points where Sie- 

 reiim purpureum is present. Preliminary experiments have been 

 carried out, and further work on a larger scale is being undertaken.

 (New Phytol. XII, p. 13—21. Jan. 1913.) 



A record of experiments conducted with the fungus Ascochyta 

 citrillina C. 0. Smith (conidial form of Mycosphaerella citrillina Gros- 

 senb.). The parasite, which causes a serious stem-disease (Tomato 

 Canker), is shown by the authors to also attack Tomato fruit Infec- 

 tion experiments prove that spores from the fruit can cause disease 

 in the stem and vice versa. The ascigerous stage was not found , 

 hence the method of propagation in England from one season to 

 another remains to be discovered. A. D. Cotton.
