at the base, and bear a single apical conidium, below which are 
several swellings of the conidiophore which indicate the typical 
cymosely branched conidiophore upon which the majority of con- 
idia have failed to develop. This species, first described by Dr. 
Thaxter, has attracted the attention of various mycologists, among 
them Dr. Clinton, who has recently published a very complete 
discussion of this destructive parasite of the lima bean.* His 
article is accompanied by illustrations of the odspores and a com- 
plete bibliography of the species.

This species, which is very closely related to P. Phaseolt, is 
said, by its author, to be very abundant on the taro, Colocasia anti- 
quorum, throughout Java, but apparently not damaging the host. 
The fungus is to be expected in other tropical countries in which 
the host is cultivated.

The present species, which is illustrated and described in great 
detail by its author, is a serious tobacco pest in the East Indies 
and may appear elsewhere at any time.
