MONOGRAPH OF USTILAGINES.* 
Professor Fischer de Waldheim has identified himself with this 
group of Fungi by his previous publications, so that a monograph 
from him is sure to be accepted with confidence and satisfaction. 
We have no doubt that this feeling will be strengthened by 
acquaintance with the work before us. Unfortunately too little 
time is devoted now-a-days by Mycologists in the preparation of 
careful monographs. It is but rarely that such works make their 
appearance, although so urgently required. The acquaintance 
which we have so recently made with the excellent monograph of 
the Myxomycetes by Dr. Rostafinski, and now with the smaller and 
less pretentious monograph of the Ustilaginece, by Fischer de 
W aldheim, confirm us in the opinion that this is the most needful, 
and most satisfactory labour to which a competent Mycologist can 
direct his energies. 
This Monograph contains an enumeration of all the species 
known to its author, arranged under seven genera, and to each 
species is attached a list of the plants on which it has been found. 
There are one hundred and twenty-seven species, besides a few 
doubtful forms at the end.
