EISTDOTHIA PARASITICA AND RELATED SPECIES. 57 



As Tachingko is 300 miles south of Changli, where E. parasitica was 

 first collected by Meyer, and Yatyeko is 500 miles west of Tachingko, 

 it seems highly probable from the collections that E. parasitica is 

 widely distributed in China (fig. 5). 



Meyer, writing from Hangchow, July 1, 1915, refers as follows to 

 the condition of the chestnuts in that locality : 



Well, I have a few interesting discoveries to report. First, there are many- 

 specimens of Castanea moUissima scattered at the bases and on the lower 

 slopes of the hills around here, and these chestnuts are seriously attacked 

 by the bark fungus, and in my estimation are going to succumb to it these 

 coming years. The chinquapins {Castanea spp. ), however, which are very 

 abundant on the higher and more sterile hill slopes, seem to be immune;

at least I did not see any evidences of damage or even of attacks. This 

 brings another interesting point to my mind. I was told in Nanking that 

 various missionaries at Killing, the great summer resort in central China 

 for missionaries, were cutting down their chestnuts, v as the tops were all 

 dying, due to borers working underneath the bark. 



Meyer has since stated to the writers that he believes the de- 

 struction of the chestnut at Kuling is due to Endothia parasitica 

 rather than to borers. 



In the writers' earlier publication the following statement was 

 made (76, p. 297) : 



The Chinese organism has thus been shown to be practically identical with 

 the American in all its morphological and physiological characters and in 

 the production of the typical chestnut blight and the pycnidial fructifications
