The name. J\ilsa Mali, first appeared in a list of important fruit 

 diseases of North Island compiled by Sapporo Agricultural Col- 

 lege, which was exhibited at the Fifth Industrial Exposition held at 

 Osaka during 1903-04 ("Sapporo Nogakko Hen, Hokkaido Juyo 

 Kwaju Uyogai" n. d., printed before April i, 1903), later described 

 by Y. Takahashi and H. Okamoto in Hokkaido Noji Shikenjo Iho 

 (Circular of the Hokkaido Agr. Exp. Sta.) No. 5: 39-41, fig. 18, 

 published March, 1908. A more detailed account of the fungus 

 was given by Dr. A. Ideta in his Nippon Shokubutsu Byorigaku 

 (Handbook of the Plant Diseases in Japan) ed. 4. pt. i (1909), 

 pp. 295-297, where the original drawing of Prof. G. Yamada is 

 first printed and the dimensions of ascopores are given as 8 X 

 1.5 /A. Cultural tests were recently reported by Dr. T. Hemmi in 

 Trans. Sapporo Nat. Hist. Soc, 6-: 146-152 (July, 1916), and in 

 Journ. 'J'nhuku Imp. L'niv., Coll. of Agric, 7*: 2//-28J (Aug., 

 1916), where the activity of the growth is stated to be remarkably 

 accelerated by an addition of 0.1-0.2 per cent, pyrotannic acid or 

 0.8 per cent, citric acid to the culture medium.
