ENTOMOPHTHORE^. 



Gonicliopliores simple or brauclied, generally 

 emerging from the matrix ; zygospores formed by the 

 conjugation of two contiguous cells, or two branches 

 of the same hypha, or arranged in a scalariform 

 manner between two distinct hyphae ; azygospores 

 are known in some species. 



The members of the present family somewhat 

 resemble the SajprolegniesQ in habit, but are quite 

 distinct in the mode of formation of the sexually 

 produced resting-spores and in the gonidia not being 

 motile. A considerable number of species are known 

 in Europe, and undoubtedly careful research will add 

 considerably to the number of British forms. 



Analysis of the Genera, 



A. Parasitic on insects. 

 Em}:>usa. Gonidiophores simple. 

 Entomoplithora. Gonidiophores branched. 



B. Saprophytic on excrement of batrachians. 

 Basidioholus. Gonidiophores very much incras- 



sated at the tips. 



Empusa, Cohn. 



Mycelium developed within the living bodies of 

 insects ; gonidiophores colourless, simple, or sparingly 

 branched, emerging in an erumpent manner after the 

 death of the insect ; gonidia terminal, smooth ; 

 resting-spores, as azygospores, produced from hyphge 

 in the body of the insect or from the germination of 

 the gonidia.
