and each bears a spore, formed by abstriction (figure 8). I was 
unable to see, either in fresh or alcoholic preparations, any 
‘partition wall between the conidiophores and the hyphe from 
which they arise, but do not feel entirely convinced in regard to 
the matter, as I found it difficult to separate them well, owing to 
the compact interlocking of the branches. Swollen hyphe with 
granular contents (figure 10) were a few times seen among the 
conidiophores, but they could hardly have been paraphyses. No 
sterile hyphz projected beyond the hymenium under ordinary 
circumstances. When the dead larve are placed in a damp at- 
mosphere over night, the mycelium grows out a millimeter or so 
beyond the surface of the body in straight or somewhat coiled 
hyphz (figure 7); these do not appear to be elongated econidio- 
phores, or true paraphyses, but a luxuriant growth of the my- 
celium. 
The spores are very regular and uniform in size (figure 3). 
When mature they are projected from the body of the larva, as 
in the common house-fly fungus, and like those adhere to what- 
ever they touch. Spores gathered in May and kept dry till No- 
vember measured, when examined in water, a little less than 
fresh ones, 21-27» by 6-8», had one end slightly pointed, and 
exhibited a central non-granular spot (figure 2). Fresh spores. 
are uniformly granular,and both endsare the same shape. They 
germinate in water in two to six hours by pushing out one to 
several tubes which grow irregularly and to indefinite length 
(figure 4). The protoplasm is filled with vacuoles, but does not 
all collect at the advancing ends of the hyphe nor are there septa 
formed as in the closely ‘related E. spherosperma Fres. Their 
behavior when germinated in moist air was not observed. Spores 
kept upon glass in the laboratory gave but a small per cent. of 
germinations after five days. 
is fungus is intimately related to E. spherosperma Fres. 
(E. radicans Brefeld), the habit of growth being the same so far 
as investigated, but differs in ultimate shape of spores, septation 
of hyphe, the various measurements, ete. Although observed as 
late as Nov. 20, when cold weather set in, no mummified larvee 
an epidemic of economic importance ; whether it could be prop- 
agated at will is yet to be determined by experiment.
