 in Japan. (Transaction of the Sapporo Natural History 

 Society, Vol. I. Part. 1. 1905-6, p. 97-109). (Japanese with 

 English resume ). 



Sclerotinia fvuetigena (Pers.) Schrot. on apple and pear, 

 Sclerotinia laxa (Ehrenb.) Aderh. et Ruhl. on plum and 

 apricot, and Sclerotinia cinerea (Bon.) Schrot. on cherry are 

 all found in Japan. Fruits are the portions generally attacked 

 by these fungi. The cases, where the flowering branches are 

 affected, are only known in apple and cheriw. The former is 

 more prevalent in northern Japan, often doing great damage. 

 According to the author's observations, the young leaves on a 

 flowering branch seem to be the portions commonly attacked 

 at first. The discolored portion generally appears along the 

 midrib. The mycelium of the fungus reaches the branch by 

 growing along the vascular bundle and finally fills the cavities 

 of vessels. Thus it hinders the ascent of sap, causing the 

 withering of flowers and leaves. On the discolored spots on 

 the leaves and branches, microconidia or macroconidia may be 

 produced according to circumstances. 



Attention is drawn to the probable identity of Monilia 

 Kusanoi P. Hexxings on the Japanese cherry, Prunus Pseudo- 

 cerasus, with Sclerotia cinerea.
