Culture methods with TJredineee, M. A. (Ivrleton {.Jour. Appl. Micr<ii<. and 

 Lab. MctJtodx, r, {190ii), X<>. 1, pp. ^109-^114).— ^n^^igestu ma are given of mctliods for 

 the cultivation of various Uredinea', the methods of germinatidn and inijculation 

 being described and a nunil)er of suggestive studies being indicated. 



Some injurious fungi occurring on cultivated plants in Dutch East Africa, 

 P. Hennings {Notizhl. K. Bot. Garten u. Mus., Berlin, 3 {1903), No. 30, pp. 2.39-243).— 

 Descriptions are given of a number of new species of fungi which are found occurring 

 parasitically on economic plants. Among those described are Anterina stuhhnnnni on 

 bananas; Mlcrofhi/riuin coji'eie on coffee; MijcosplixreUa tnniarindi, and GlceoKporiuin 

 tamarindi on tamarind; Mucrophoma manihoiiK, Ai^cocJn/ld niauihotis, and Gheor.porinm 

 ninviJiotis on cassava; Tmlhdd raniUie on vanilla, and J[rliiiint}tn^j)i)riiiiii trilici on 

 wheat. 



Two new fungi from Ohio, F. Buhak {.Jonr. Mi/coL, 9 {1903), JVo. 65, pp. 1-3). — 

 Descriptions are given of Stanniarin sp. , which is parasitic on species of Equisetum, 

 and on Cerco.spora kellermani, which occurs on hollyhock. 



Concerning the name and distribution of TJrophlyctis bohemica, P. Magnus 

 {CndU. Bald. u. Par., ^\ Ah(., 9 {1902), No. 24, pp. 89.5-897 ) .—The author discusses 

 the identity of iSipicJit/triam trifaUl described by Passerini as occurring on the leaves 

 of the common red clover and Urophliictis hoheniira, recently described by Bubak as 

 parasitic on TrifoVnini moutainim. Eecent studies have shown that the si)ecies form- 

 erly referred to Synchytriuui is a TJrophlyctis, and the author believes the 2 species 

 are identical, the proj)er name of the fungus l)eing U. irifolii. The species seems to 

 be widely distributed throughout Europe, where it occurs as a parasite on various 

 cultuies. 



A contribution to the micology of Liguria, A. Magnagui {Separate from Atli 

 Ind. Pot. Viiir. Pavia, 2. .ser., 8 {1902), pp. 13). — Lists are given of some parasitic 

 fungi, a number of which are of considerable economic importance. New species 

 are descril)ed as follows: Macrophonia lignsticiun on hydrangeas, M. helicinum on ivy, 

 Ci/tosporella clfri on orange, Spharoj»<is magiioliw on magnolias, Ghrosporiam hegcjnix 

 on begonias, and CoUetotrichum pollaccii on Japanese locjuat. 



The development of a new parasitic micromycete, R. Farneti {Separate from 

 Atti hixt. Bot. I'liir. Paria, 2. scr., 7 {1901), pp. 42, />fc'. ^). — A description is given of 

 a new ])arasite of Salvia to which the name Oidiuni Iwrminl is given. The develoj)- 

 ment and polymoi-phic ])hases of the organism, as shown by numerous culture exper- 

 ments, are fully described. 



Notes on two diseases of cotton, F. Fletcher {Jonr. Khediv. Agr. Sac. and 

 School Af/r., 4 {1902), No. 6, pp. ^.^8-241). — In continuation of a previous report on 

 the wilt disease of cotton (E. 8. R., 14, p. 579), the author states that what is known 

 in this country as sore shin, damping off, or seedling rot is responsible for a consider- 

 able portion of the loss of cotton in Egypt. In addition to this disease the cotton 

 wilt, due to Neocosmospora vacinfecta, is quite prevalent, <'ausing considerable loss, but 

 the disease is apparently not as injurious as is reported in this country. This is 

 believed to be due to the resistance of some Egyptian varieties to this fungus. 

 Among the varieties in general cultivation Abbasi seems to suffer mi ist fri mi l lie wilt, 

 and Mitafifi. and Yannovitch the least. The author shows that a number of other 

 plants are subject to attack of the wilt fungus and in arranging rotation of crops 

 these should be carefully excluded. 



Experiments with rust-resisting wheats, W. L. Summers {.Innr. Agr. and Ind., 

 South An.stralia, {1903), No. 7, pp. 449-455).— A report is given of cooperative experi- 

 ments with 16 varieties of rust-resistant wheats, the trials being made in 9 different 

 localities. In 1901 the crops suffered severely from rust, l)ut during the year c )vcrt'd
