Mycological notes, F. Bubak and J. E. Kabat (Hedwigia. Jfl (1908), No. 6, 

 pp. 35Ji-361t, fig. 1). — In a taxonomic discussion of several species of fungi from 

 Bohemia, the following of economic importance are described : Phyllosticta 

 albomaculans n. sp. on the leaves of Prurius padits, Phyllosticta iseraiia n. sp. 

 on the leaves of Sallx fragtlis, Ascochyta wsculi n. sp. on JEsculus hlppocas- 

 tanum bicolor, Ascochyta grandispora u. sp. on Symphoricai'pus orMciilatus, 

 A. lappce on Lappa minor, A. pallida n. sp. on Acer platanoides bicolor, Asco- 

 chyta pruni n. sp. on Prunus padus, A. populicola n. sp. on Populus alba, A. 

 symphoriw n. sp. on Symphoricarpus raccmosa, A. syringicola n. sp. on Syringa 

 vulgaris, and Uromyccs bdinnlerianus n. sp. on Melilotus alba. 



New or rare fungi, F. Btjbak (Ann. MycoL, 6 (1908), Xo. 1, pp. 22-29, figs. 

 8). — In a taxonomic discussion of several species of fungi the author describes 

 as new Puccinia bdiimlcriana on Anthenvis tinctoria from Hungary, Phyllosticta 

 malkoffli on Gossypium herbaceum from Bulgaria, and Ascochyta ferdlnandi on 

 Sambiicus ebulus, also from Bulgaria. 



Report on cultures of Uredineae, E. Fischer (Centbl. Balct. [etc.], 2. Abt., 

 28 (1910), No. Jf-5, pp. 139-152). — The author reports successful inoculation 

 cultures as follows : ^cidiospores of /Ecidium euphorbice gcrardiance from Eu- 

 phorbia geradiana on Saponaria ocymoides produced both uredo and teleuto- 

 spores of XJromyces caryophyllinus, but the attempt was unsuccessful on Dian- 

 thus silvestris. Teleutospores of Gymtwsporangium tremelloides from Junip- 

 erus communis produced secidia on Sorbus aria, S. hybrida, S. latifolia, and 8. 

 chamcemespilns (in one instance). JEcidiospores of Ochropsora sorbi from 

 Anemone nemorosa produced sori on /S. auciiparia, 8. aria, 8. fennica, 8. ameri- 

 cana, and Pints communis, and fecidiospores from the same host also produced 

 sori on Arnncus silvestris. Teleutospores of Puccinia albulensis from Veronica 

 alpina produced sori on V. bellidioidcs and V. aphylla. 



Apparatus for the treatment of grain by the hot-water method, R. Schan- 

 DER (Deut. Landw. Presse, 87 (1910), No. 30, pp. 333, 334, figs. 5).— Descrip- 

 tions and figures are given of several types of apparatus for use when treating 

 wheat, barley, etc.. by the hot-water method for the loose smut of grain, to- 

 gether with a brief account of this method and the results obtained by its use. 



Experiments on the control of loose smut of whea.t and barley by means 

 of hot water and hot air, R. Schander (Landiv. Centbl. Poscn, 1910, No. 5; 

 ubs. in Centbl. Bald, {etc.], 2. Abt., 28 (1910), No. 9-11, p. 302).— The results 

 are given of tests with wheat and barley seed, in which the grain after soaking 

 for 4 hours in cold water was placed for 10 minutes in hot water at 56° C, and 

 also at 54°. In the first instance the smut was entirely destroyed, and in the 

 second, practically so. 



Tests of the hot-air treatment did not give satisfactory results. 



On the control of the loose smut of barley, P. Gisevius and Bohmer (Illus. 

 Landiv. Ztg., SO (1910), No. 77, p. 125. fig. 1). — The authors describe a drying 

 apparatus to be used in the hot air method (E. S. R., 23, p. 46) of combating 

 loose smut of grain, which is smaller and cheaper than those usually described 

 and offered for sale, and is intended for farmers planting small areas to barley 

 where a large machine is unnecessary. 



Relative rust resistance and yield of various varieties of wheat and oats, 

 W. J. Lamont (Agr. Jour. Cape Good Hope, 31 (1910), No. 3, pp. 2Jf3-2J,8).— 

 The author compares 22 varieties of wheat tested during 1909 as to rust re- 

 sistance, growing characters, bread-making qualities, milling properties, and 

 yield. 



The old Rietti, a variety imported in 1S96, has so far proved to be the only 

 wheat which has withstood rust uniformly well in the Western Province, but 

 it is not a good milling wheat, is very late, and sheds its grain very easily. Of
