Hendersonia Theae K. Hara sp. nov. Chagyokai (Tea Jour- 

 nal) 14 12 : 22-23. T. 8, December, 1919. (Japanese.) 

 Pycnidia globose or depressed-globose, 60-130 ^ in diam., im- 

 mersed, later slightly erumpent, pycnidial wall parenchymatous, 

 composed of angular cells of 4-7 jm in diam., apically ostiolate; 

 ostiola papillate or warty, with opening 11-15 /x across; pycno- 

 spores broad-ellipsoid or broad-fusoid, broadest near the middle, 

 narrowed toward both ends, at first hyaline, finally changing to 

 yellowish-brown, 3-septate, somewhat constricted, 7-10 x 4-5 ,u. 

 Parasitic on the leaves of Thea sinensis. ' 



Type locality : Shidzuoka-ken Abe-gun Okawa-mura, October 

 24, 1918. (K. Hara.) 



Foliicolous, appearing mostly at the leaf tips, on spots that in- 

 crease their area downward by degrees toward the leaf base with 

 definite but undulating border lines. The infected area is at first 

 dark brown, but later it changes color, becoming gray, and minute 

 spottings of fungus bodies appear somewhat sparsely on the sur- 

 face. The lower surface of the diseased area is light brown in 

 color.

Since March, 1919, Kanesuke Hara has been publishing in 

 Chagyokai (Tea Journal) a series of papers dealing with the 

 diseases of the tea-plant, m which he describes a number of new 

 species of fungi. The translations given here and in the last num- 

 ber of New Japanese Fungi (Mycologia 12°: 330-332) cover 

 nearly all of those published in 1919; the rest of his new species 

 will be given in the subsequent numbers of this series.
