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

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

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

 mersed, later slightly erumpent, pycnidial wall parenchymatous, 

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

 ostiola papillate or warty, with opening ri-15 jx 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 /x. 

 Parasitic on the leaves of Thca 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. ])ut 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, in 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 nvmibers of this series.
