530), Beneke (1948: 29, pi. 1, fig. 18), United States; Sparrow (1933b: 

 535; 1936a: 459), Great Britain; Hohnk (1935: 221, fig. 1 c-h), Ger- 

 many. 



Hohnk's species appears to differ in no essential features from Mon- 

 oblepharis ovigera. Though proliferation of the sporangium in the latter 

 is rare it is by no means lacking. It is possible that the very small struc- 

 tures resembling sexual organs and the smooth-walled spherical cysts 

 found by Sparrow (1933b: pi. 20, figs. 21-22, 24, 27) among sporangial 

 plants of this species indicate that it has a type of sexual reproduction 

 similar to that of Monoblepharella taylori.

EXCLUDED SPECIES OF MONOBLEPHARIS 



* MONOBLEPHARIS LATERALIS Hine 



Amer. Quart. Micro. Journ., 1 : 141, pi. 7, figs. 4-21. 1878-79 



This is doubtless a saprolegniaceous fungus, probably infected by a 

 flagellate, a situation also found in Archilegnia (see p. 796). 



REJECTED GENUS OF THE MONOBLEPHARIDALES 



* MYRIOBLEPHARIS Thaxter 



Bot. Gaz., 20: 482, pi. 31, figs. 1-5. 1895 



After many years, Minden's (1915) astute conclusions have been 

 verified concerning this paradoxical form. Waterhouse(1945) has proved 

 conclusively that Myrioblepharis paradoxa Thaxter either is a Pythium 

 or a Phytophthora parasitized by aciliate, probably a species of Prorodon.
