tributed along the arm (as Van Tieghem and Le Monnier state 
them to be), but both lie in the distal half (figs. 7 & 17). Van 
Tieghem and Le Monnier have represented rays with three septa 
(J.c. fig. 129), but in no case have I seen more or less than two 
in any of my specimens. 
The upper surfaces of the proximal and middle segments of 
each ray become studded with minute, rounded eminences—the 
sterigmata—each of which bears a conidium. The distal segment 
of the ray always remains smooth and free from spores (fig. 7). 
he conidia are hyaline, elongated-fusiform bodies with acutely 
pointed ends. They measure ‘01 mm. in length and :003 mm. in 
breadth. They are arranged upon the sterigmata in a very regular 
manner, with their long axes directed obliquely upwards in the 
manner represented in 
looked down upon from above (fig. 9). The number of rays may 
vary widely; in my specimens I have counted all numbers between 
ree and seventeen (cp. figs. 9 & 10). Van Tiegh on-

Besides the formation of these characteristic conidiophores, 
Van Tieghem and Le Monnier described the deve opment o 
chlamydospores by these plants. In one of my hanging-drop 
cultures numerous chlamydospores appeared upon the hyphae,
