indicated. The artist has not overlooked little details such 
as the annular zone on Coprinus atramentarius, showing that 
he is a mycologist as well as an artist. The plates have a 
natural appearance as though the plants grew, the author 
having avoided the stiff, inflexible effect we notice in manv 
illustrations of American agarics, as though they had been 
cast in a mold. 
We regret we cannot endorse the author’s coloring of 
the plates as we do the drawings, but we recognize how 
difficult it is to reproduce the colors of nature. In this re¬ 
gard however, they are no more at fault than many other 
plates, both of this country and of Europe. The plates will 
be of great service to anyone engaged in the study of 
mycology, and at the price offered should be in every 
worker’s hands. 
47—THE HOMES OF EUROPE. 
Through the kindness of Rev. G. Bresadola we have re¬ 
cently received a full set of specimens illustrating the Fomes 
which occur in Europe, and a manuscript key to the various 
species described, showing Prof. Bresadola’s views regarding 
their nomenclature and disposition. Prof. Bresadola has given 
special study to the Polyporii and has compared specimens 
in various museums of Europe, including the collections of 
.the illustrious Persoon and Fries, and while this “key” was 
sent to me for my private information, I consider it too val¬ 
uable to be lost to the world and take the liberty of publish¬ 
ing it. It is a matter of gratification to me that Prof. Bresa¬ 
dola’s views tend to the reduction of species, lor the undue 
publication of species on slight differences or insufficient 
knowledge of existing species, is one of the chief difficulties 
we must contend with in the study of* Mycology. The term 
“unknown” in the key must be read “unknown to Bresadola” 
to give it its true sense. We hope at an early date to pub¬ 
lish a paper on the American species of Fomes in the light 
thrown on them by comparison with Prof. Bresadola’s set from 
Europe. 
Prof. Bresadola divides the genus into two genera. 
Fomes and Ganoderma, the latter distinguished by its col¬ 
ored spores and the shiny rigid crust of the pileus. The 
species marked with a * belong to Ganoderma.
