CURRENT LITERATURE. 
Last volume of a great work.* 
The task of collecting and issuing in uniform manner all the specific 
descriptions of fungi ever published, although requiring prodigious 
r, has been accomplished by the author of the Sylloge Fungo- | 
rum in a remarkably short time, and the final volume now lies before 
The ten volumes of the work contain about forty thousand species. 
How many of these names are synonyms is the part of the monograph- 
er and special student to determine. Excellent judgment has been 
shown throughout in the compilation, and the work will not only be 
a monument to the perseverance of the author, but of inestimable and 
lasting service to mycologists. 
The present volume does not differ essentially in its make up from 
the preceding, except in possessing a universal index to the cohorts, 
families, genera and their synonyms of the full ten volumes. The 
series closes most appropriately with an enumeration of fossil fungi, 
embracing 331 numbers, compiled by Dr. A. Meschinelli. 
Although this is the last volume of the work as projected, Dr. Sac- 
cardo offers to issue addenda, if authors will kindly continue to send 
him their publications. He states that at the time this last volume 
came from the press (June, 1892,) some fifteen hundred species, incred- 
bile dictu, had already come in, too late to be included. Such evi— 
dence of activity in the collection and study of fungi indicates how 
highly serviceable such addenda must be to all working botanists.

flowers in the heart of Switzerland. From these early influences Les-

évoted the greater part of his life. In the year 1848 he came to
