Rhizophydium codicola Zeller 

 Publ. Puget Sound Biol. Station, 2: 122, pi. 20, figs. 1-4. 1918 



Sporangium sessile, spherical to almost obpyriform, 16-24fj. in diam- 

 eter, with a smooth colorless relatively thick wall; rhizoidal system 

 extensive, coarse, much branched, the ultimate branches delicate, 

 arising from a stout irregularly expanded somewhat lobed main axis; 

 zoospores spherical, 2.5-3 u, in diameter, with a colorless basal glob- 

 ule and a long flagellum, emerging through a large lateral irreg- 

 ular aperture in the sporangium wall; resting spore not observed.

"Zoosporangium epibiotic, sessile, globose or subglobose, 10-15 u. 

 in diameter, hyaline, smooth, thin-walled, with a broad apical or rarely 

 sublateral pore. Rhizoid (haustorium) simple, filamentous, short. Zoo- 

 spores produced 10-20 in one zoosporangium, globose, 2—3 {x in diam- 

 eter, with one globule and posterior 10 [x long flagellum, moving in 

 zoosporangium and then darting away through pore. Resting spore 

 not observed" (Kobayasi and Ookubo, be. cit.).
