 fig. 1. June, 1912.) Sawada suggests that more noticeable dif- 

 ference may be revealed if they are closely compared as in the case 

 of species of Bremia. (See Mycologia iP: 84-86. March, 1919.) 



Colletotrichum Boehmeriae K. Sawada sp. nov. in Taiwan 

 Hakubutsu Gakkwai Kwaiho (Journ. Formosan Nat. Hist. Soc.)

Foliicolous or caulicolous ; spots scattered, cinereous with brown 

 margin, orbicular and 1-2 mm. diam. on leaves, when on stem, 

 forming orbicular, elliptical or fusiform spots, occasionally causing 

 longitudinal rupture of the host epidermis, 1-6 x 0.8-2 mm. in

 ophores dense, short, terminated by conidia; conidia colorless, 

 cylindrical or occasionally clavate, straight, obtuse at both ends, 

 granular, 14-19 x 4-5 /x; setae dark-brown, tapering toward the

Parasitic on Ramie (Boehmeria nivea). 



Type locality : Taihokucho Chonaihosho, Formosa. June 29, 

 1914 (A. Imachi). 



Stem infection causes bad staining of the bast fibers, which is 

 hardly removable when the fibers are bleached. The infected 

 plant, therefore, yields only lower grade fibers of less commercial 

 value.
