Sasaki and two species of facultative parasitic fungi, Glomerdla Cinnamomi and 

 Pestcdozzia Gamphori grow on the diseased portion of the bark of the tree and

My cordial thanks are due to Dott. Fridiano Cavara, Prof. Dr. Kingo Miyabe, 

 Prof. Kotaro Shirai and Mr. Yoshinao Takahashi, with whose kind assistance my 

 studies on the plant diseases have been carried out.
