were less opaque, dark chocolate-brown in color and with the 
tubercles clearly discernable in the unbroken epispore. The proto- 
plasmic contents were sparse and the oil globules small and 
numerous. That these were not immature stages is shown by the 
fact that three or four weeks time produced no change in the culture. 
A series of camera-lucida drawings were made of several of the 
abnormalities found in the culture. The typical zygospore of the 
species is subglobose and borne between a pair of almost equal sus- 
pensors which taper from the spore to the hyphae from which they 
arise and with which they are continuous. The zygospore repre- 
sented at figure 6 is normal except in regard to the suspensors 
which are separated from their hyphae by septae and are sharply 
curved at the base. Figures c and d represent types of poorly 
developed zygospores both of which were very light brown and 
almost destitute of protoplasm. Figures e and f represent partheno- 
spores. These are formed by a single gamete and are said to have 
the same function as the zygospores. The term “ azygospore '' is 
usually applied to these spores but with questionable propriety as, 
being formed without the union of gametes, either equal or unequal, 
they are certainly not entitled to be called zygospores. Moreover, 
the term azygospore is not used to designate similar structures 
among the zygosporic Algae, nor are equivalent spores among the 
oosporic Algae and Fungi referred to as ‘‘anoospores.’’ Figure e ' 
represents both the gametes as having formed smooth, light colored 
Spores, while in figure f but one spore was formed, the other pro- 
gamete not even cutting off a gamete. : 
By far the most interesting of these abnormal spores is that 
illustrated in figure a. This spore has the appearance of being 
double in structure; but at no point were the suspensors entirely 
separated, although both suspensor and spore were deeply grooved. 
This abnormality may have been formed by the fusion of closely 
approximated gametes; or, as is to the mind of the author much 
moré probable, we have here an example of fasciation in the 
mou 
II. A NEMATODE IN HYDROGERA KLEINII. 
While engaged in a study of the local species of Mucorales of 
Tippecanoe County, Indiana, a mass of horse dung which was 
Covered with ZZydrogera Kleinit (van Tiegh.) Kuntze, ( Pilobolus 
Kleinii van Tiegh ) was brought into the laboratory the 16th of 
October. The sporangiophores averaged a centimeter in height 
and were of a bright yellow color. The spores were large (14-20 a)
