A ne"w parasite of sugar beets, L. Trabut {Rev. gen. Bot., 6 

 {1894), N^o. 70, pp. 409, 410, yl. 1). — Tlie sugar beets iu the experimental 

 fields of the agricultural school at Eomba presented in May of the 

 past j^ear a great number of tuberosities due to a fungus. They 

 usually appeared at the insertion of the first leaves and formed a com- 

 plete circle underneath the leaves, equaling in weight the beet root 

 itself. The surface, at first greenish-yellow, became gray or nearly 

 black, and finally lobed and tubercled. If a section be made of oue 

 of the attacked tubercles a watery parenchyma may be seen, with here 

 and there running through it some irregular fibrovascular bundles. 

 Numerous dark areas will be observed, the masses of spores. Some 

 plants may be affected and not show the swollen places, but the nutri- 

 tiou will be interfered with and under different circumstances the 

 tubercles may be developed. 



No reference is given to any trials having been made for the supjires- 

 sion of the disease. 



The author presented a note^ on this fungus under the name of 

 Entyloma lephroidenm, a species of UstUaginew, but Saccardo, to whom 

 specimens were submitted, decided it was not an Entyloma, but differed 

 from it by the swollen spore-bearing terminal branches, and he pro- 

 posed for it the generic name (Edomyces, characterized as follows: 

 Mycelium, intercellular, filaments very slender. The spore-bearing 

 branches bear a terminal spore or swollen vesicle. Spores, rarely 

 solitary, more frequently groui)ed iu great numbers in the alveoli. 

 Epispores, swollen, brown, smooth. Promycelium and sporidia not 

 seen. According to this determination the si)ecies becomes (Edomyces 

 lephroides, described as follows: Swellings, fleshy, very large, devel- 

 oped at the expense of the leaves or buds, lobed, showing in section 

 a white parenchyma with numerous black spots composed of single 

 spores or masses of them, most frequently groui)ed together, borne 

 npon very slender and at length swollen branches. Vesicles spherical 

 or slightly flattened, with a short pedicle inserted in the center of the 

 depressed face. Epispores swollen, smooth, brown, 35/^ in diameter. 



Report of botanist and entomologist {Florida Sta. Bui. 24, pp. 

 16-19, fig. 1). — The author reports preliminary experiments with Bor- 

 deaux mixture and ammoniacal copper carbonate for eggplant blight. 

 The leaf spot fungus {Phyllostiata hortorum) was also i)resent. A report 

 is also made on the successful use of Bordeaux mixture aud eau celeste 

 for the shot-hole fungus of plums. Par Oidium, used for the same 

 disease, was without efl:ect. 



While testing some tobacco seed it was found that some of the seed- 

 lings were infested by nematodes {Reterodera radicicola.) causing their 

 destruction in a few days. The seedling is attacked as soon as 

 sprouted, or shortly afterwards, the radicle assumes a greatly swollen
