110 THE LOWER FUNGI— PHYCOMYCETES 



alga, stores starch, and is most closely related to another algal 

 genus, Phyllobium Klebs {Bot. ZeiL, 39: 249, 1881). Its para- 

 sitic habit and its lack of chlorophyll nevertheless indicate 

 fungous tendencies. The life history and cytology of the 

 species are discussed by Griggs (1912), Atkinson (1908 a, b), and 

 Ramsbottom (1913). In gross aspect the organism resembles 

 Synchytrium (see p. 13). 



6. Mitochytridium Dangeard. 



See discussion under Ancylistales. 



7. Polyrhina Sorokin. 



The single species, P. multiformis Sorokin (Fig. 42), is appar- 

 ently the same as Harposporium anguillulae Lohde (see Zopf, 

 1888, for good figures). Its position is doubtful. 



8. Rhizidiocystis Sideris (Phytopathology, 19: 376, 1929). 

 Based on R. ananasi Sideris, parasitic in root hairs of pineapple. 



Placed by the author in the Cladochytriaceae.
