 text fig. 4, pi. 12, figs. 20-27. 1927. 



Mycelium exceedingly tenuous, sparingly branched, hyphae about 5 

 jx at the base, tapering to 1.8-2 fx, in diameter; sporangia narrowly 

 cylindrical, but distinctly broader than the hyphae, on which they are 

 usually terminally placed, 18—36 fj., in length by 5.4-7.2 \x in diameter, 

 new sporangia formed by proliferation partly or wholly through the 

 apex of the old one or occasionally by cymose branching; zoospores 8 

 \x long by 5 \x in diameter; sexual reproduction not observed. 



Saprophytic on submerged twigs of various types. Lagerheim (loc. 

 dr.), Sweden; Thaxter (F.), Sparrow (1933b: 534, pi. 20, fig. 26; 1933c: 

 530), United States; Laibach (loc. cit.), Hohnk (1935: 220, fig. 1 a-b), 

 Germany; Sparrow (1933b: 534), Great Britain. 



This and the following species may belong in Monoblepharella.

Mycelium often profuse, composed of very delicate occasionally 

 branched hyphae 3-4 \x in diameter; zoosporangia terminal or inter- 

 calary, ovoid, 10-13 [i in diameter by 23-33 fx in length, rarely prolifer- 

 ating; zoospores often formed in two rows, 8 (x long by 6 jx in diameter;
