Monohlepharis, Cornu. Ann. Sc. Nat. ser. v. vol. 

 XX. p. 84 ; Sacc. Syll. vii. p. 277. 



Distinguished by the motile antherozoids and 

 zoogonidia being nniciliate. 



Monohlepharis spliserica, Cornu. (figs. 26, 27). 



Mycelium branched, aseptate, about 5 /x diameter; 

 oogonia monosporous, terminal, solitary, rarely in

On rotten leaves in stagnant water. Rare. 



Resembling in appearance a species of Pythium or 

 Saprolegnia, but distinguished by the motile uniciliate 

 antherozoids contained in a cut-off portion of the

Fam. 4. Entomophthore^. 



The species included in the EntomophthorecB are 

 for the most part entomogenous, or parasitic on insects, 

 but a few species not yet recorded for Britain are 

 met with on fungi, in the prothalli of ferns, or on the
