This disease was at first discovered by Masazo Hotta at Aratama 

 district, Inasa-gun, Shidzuoka-ken, and reported in the Annual Re- 

 port of Shidzuoka-ken Agricultural Experiment Station (for the 

 fiscal year T. 5, 1916). Hara in the Byochu-gai Zasshi states that 

 the disease is serious in the vicinity of Hamamatsu and also occurs 

 in the Mie Prefecture.

 Stromata scattered or gregarious, at first immersed, later erum- 

 pent, pillow-shaped or wart-like, sometimes confluent, afterwards 

 with rounded margin adhering to substratum, 0.8-5 mm - m diam., 

 surface orange-yellow or dirty-yellow, rugose with black perithecial 

 spots, inside orange-yellow, somewhat membranaceous in structure, 

 with imbedded perithecia ; perithecia globose or ovoid, dark-col- 

 ored, 300-350 x 180-300 fi, wall carbonaceous or parenchymatous, 

 dark-colored ; ostiola terminal, forming wart-like protrusions on 

 the surface of stroma, opening one, round, 80-100 p across; asci 

 cylindrical or clavate, apex rounded or somewhat mamelon-shaped, 

 base tapering to pedicel, 150-170 x 20-25 paraphysate, octo- 

 sporous ; paraphyses filiform, forked, longer than or equal to the 

 asci, 1-1.5 /x across; ascospores biseriate or irregularly tri-seriate, 

 fusoid, cylindrical or clavate, rounded at both ends, straight, bent 

 or curved, or more or less lunate, with numerous biseriate oil 

 globules, giving the appearance of a septum, 6-1 i-septate, con- 

 stricted or straight, hyaline, 35-44 x 8-9 fi, germinating at both 

 ends. 



Parasitic on trunks and branches of The a sinensis. 



Type locality : Shidzuoka-ken Hamana-gun Hikuma-mura, No- 

 vember 11, 1918. (K. Hara.) 



The affected area first appears on one side of branches or trunks 

 as a spot of dark pink or gray color, and by increasing its size it 

 entirely surrounds the bark, simultaneously spreading upwards and 

 downwards. The stroma then makes its appearance as dirty- 

 yellow or in some rare instances pinkish-yellow spots, raised from 

 the diseased surface like warts or a pillow-shaped elevation or 

 sometimes a button-shaped swelling of 0.8-8 mm. in diameter. 

 Perithecial bodies are formed on the stromata as elevated or flat
