glohijera and Champia 

 parvula. 



Furthermore I 

 have found this plant 

 growing in the epider- 

 mal layer of Dictyota 

 indica (Fig. 396). The 

 cells reached a length 

 of about 50 |i and a 

 breadth of about 25 \x. 

 The hairs are about 

 4 jLi thick. The figure 

 shows partly a piece of 

 the plant together with 

 the epidermal cell- 

 layer of the host, partly 

 a transverse section of 

 the Phæophila immer- 

 sed in the epidermal 

 layer of the Dictyota.
