h\'l>hae which enter the body of the fly bud like yeast celk, which are 

 carried to all parts of the insect's body. Later the parasitic h>-ph2 

 arise from the gemmae. Resting spores are unknovm. 



Entomopkthora is a genus of fungi inclusive of thirty species found 

 on various insects in Europe and North America. Entomophthora 

 sphterosperma has a richly branched nutritive myceliimi, which grows 

 through the body of insects. After the death of the host, the h\-phae 

 break through the surface in coimected strands part of which attach 

 the larva, or insect's dead body, to the substratum and part form a 

 thick white mantle over the surface. 



The conidiophores are in branching bundles. The conidiospores 

 are elongated eUipsoidal, 5 to 8/1 broad by 15 to 26/a long. Secondary 

 and tertiary conidia are found. The resting spores produced as zzy- 

 gospores are spheric and 20 to 35/1 broad with a smooth yellow wall. 

 It grows on larvse, especially frequent on the cabbage worm Pieris 

 brassioB in Europe and North America. 



BIBLIOGRAPHY OF THE ZYGOMYCETALES 



This is not intended to be a complete list of the works dealing in whole or in 



part with the mould fungi, but onlj' a list of the works which may prove helpful to 



the student of mycology.
