Mycologia 



On apple, causing a somewhat destructive blight disease, called 

 " Furanbyo " in Japanese. The disease first appears on the sur- 

 face of branches as brownish spots with irregular or nearly oblong 

 circumference, slightly elevated from healthy portion, then gradu- 

 ally drying out, inconsiderably sunken, more or less darkened, 

 and cracking on the outer surface, finally disclosing the pustules 

 which are scattered over the diseased surface. No secretion of 

 liquid was observed, which is usual in case of fire-blight (Hiya- 

 kebyo) caused by Bacillus amylovorus also known in northern 

 Japan. 



Type locality : Not given. Distribution : Northern part of 

 Honshu and Hokkaido. 



The name, Valsa 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 ]nyd 

 Kwaju Byogai" 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 /X. Cultural tests were recently reported by Dr. T. Hemmi in 

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

 Journ. Tohoku Imp. Univ., Coll. of Agric, 7*: 277-287 (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.
