Notes on Some South African Entomophthoraceae. 
85 
At Cedara an Entomojphthora was found to be common on cutworms 
from October to January. It occurred in two forms ; in the one conidia 
were thrown off in the usual manner, whilst in the other no conidia were 
formed, but the body of the host became filled with blackish brown resting 
spores. In both cases the hosts were fixed to the upper sides of leaves, 
etc., by means of rhizoids, but in the latter case the victim's body was 
blackened and flattened on to the substratum. There could be no doubt 
but that the two forms belonged to the same species of fungus. They 
occurred simultaneously on similar hosts, in each case the rhizoids were 
exactly similar, and in the bodies of cutworms containing the resting spores 
the remains of typical hyphal bodies could be found. 
Thaxter expresses the belief that E. virescens and T. megaspermum are 
identical, but could not be sure, as he never found the resting spores. 
Both forms were found side by side at Cedara, although no specimens were 
found which bore resting spores and conidia simultaneously. Apparently 
the fungus exhausts itself in producing either one or the other form of 
reproductive body, but not both. 
If these two forms do both belong to the same species — and every indica- 
tion points that way — then Thaxter's name E. virescens falls before Cohn's 
megaspermum and the species becomes E. megasperma. According to 
Burger and Swain (12) E. chromaphidis also produces resting spores very 
similar to the above, and no individuals were found bearing both conidia 
and resting spores at the same time.
