764 EXPERIMENT STATION RECORD. 



Cereal blights and the liming and sulphuring of the seed grain, E. Piret 

 (Agronome, 1S9S, No. 40). 



The gum flow of the sereh disease of sugarcane, A. Wieler (Beitr. Wiss.Bot., 2 

 (1S9S), pp. 29-140). 



The parasitic diseases of sugar beets ( Agr. RaiioneUe, 1S9S, No. 20). 



The biology of some parasitic fungi, M. Nordhausen (Jahrb. Wiss. Bot. [Prings- 

 heim~], 33 (1S9S), No. 1, pp. 1-46). — This paper treats of the conditions and manner of 

 infection by Botrijiis cinerea, conditions of the host plant for successful infection, 

 the occurrence of B. cinerea and related fungi in nature, and studies of.Penicillium 

 and Mucor as representatives of saprophytic life. 



On the presence of a fungus in Lolium temulentum, P. Guerin (Jour. Bot. 

 France, 12 {1898), No. 15-16, pp. 230-238, figs. 5).— The author reports finding in the 

 grain of this plant a fungus of a somewhat similar nature to the ergot of rye, and 

 thinks the poisonous properties of the plant may be due to this cause. 



Notes on the occurrence of a fungus in Lolium temulentum, P. Guerin (Jour. 

 Bot. France, 12 (1898), No. 23-24, pp. 384, 385).— Attention is called to the publication 

 by the author in August, 1898, mentioning the presence of a fungus in the grains of 

 the darnel, the name Endoconidium temulentum having been given it. This paper 

 seems to have been overlooked by Hanausek and Nestler. 1 The conclusions of the 

 different authors agree in the main, except Guerin finds this fungus on other species 

 than L. temulentum, such as on L. perenne and L. linicola, and its wholly saprophytic 

 nature is questioned. 



A comparative study of some anthracnoses, B. M. Stoneman (Bot. Gaz., 26 

 (1898), No. 2, pp. 69-120, pis. 12). 



The stem-rot disease of carnations, W. E. Britton (Gardening, 7 (1899), No. 153, 

 p. 138). — Notes on unsuccessful attempts to check the disease. Destruction of all 

 diseased plants, propagation only from healthy ones, and the use of fresh soil are 

 believed to be the most nearly successful methods of control yet known. Antirrhi- 

 nums and asters have been affected in a similar manner. That the same fungus 

 attacks these 3 plants is believed to be probable. 



A disease of the loquat, G. Quinn (Jour. Agr. and Ind., S. Australia, 2 (1S9S), 

 No. 5, pp. 400, 401, fig. 1). — The occurrence of a destructive disease of loquats, due 

 to Fusicladium eriobotryce, is mentioned. The application of Bordeaux mixture has 

 been tried and is recommended for its prevention. All diseased fruits and leaves 

 should be collected and burned. 



Rose mildew, G. Scalia (Bol. Ent. Agr. e Patol. Teg., 5 (1898), pp. 17-21; abs. 

 in Ztsclir. Pfianzenkranlc, 8 (189S), No. 5, p. 304). — The author notes an unusual out- 

 break of this fungus, and states that the atmospheric conditions had been exception- 

 ally favorable for the development and spread of the disease. Sulphur dusted on 

 the plants is recommended as treatment. Splurrotheca pannosa is also noted as 

 abundant on peach trees. 



The clematis disease, J. Jensen (Amer. Florist, 14 (1899), No. 555, p. 740). — Notes 

 are given of the disease, and quotations from various investigators seem to indicate 

 that the trouble is a physiological one. Sorauer is quoted as saying it is due to too 

 much nourishment, Avater, and heat. The Florida and lanuginosa types seem most 

 subject to the dying off that characterizes this particular disease. 



On the presence of Septoria curvata on Robinia, A. Mori (Staz. Sper. Agr. 

 Ital., 31 (1S9S), No. 5, p. 499). — Notes the attack of this fungus ou Robinia pseudaca- 

 c\a~. The circular brown spots, with their numerous perithecia, are said to be quite 

 abundant on the leaves and have proved very destructive to the trees. 



The cause of chlorosis in green leaves, C. Mohr (Garlenwelt, 2 (1898), No. 48, 

 p. 569; abs. in Bot. Centbl., 76 (1S9S), No. S, p. 2S2).— The author does not consider 

 chlorosis a disease, and for its prevention recommends the use as a fertilizer of a
