CEOGRAPHICAL DISTRIBUTION. 281 
added considerably to the number of Discomycetes, for which 
the climate seems to be favourable; but, as a whole, it may be 
concluded that Western and Northern Europe are much better 
explored than the Eastern and South-Eastern, to which we might 
add the South, if Italy be excepted. 
We have only to add, for Europe, that different portions of 
the German empire have been well worked, from the period of 
Wallroth to the present.* Recently, the valley of the Rhine has 
been exhaustively examined by Fuckel;+ but both Germany and 
France suffered checks during the late war which made their 
mark on the records of science not so speedily to be effaced. 
Denmark, with its splendid Flora Danica still in progress, more 
than a century after its commencement,{ has a mycologic flora 
very like to that of Scandinavia, which is as well known. 
If we pass from Europe to North America, we find there a 
mycologic flora greatly resembling that of Europe, and although 
Canada and the extreme North is little known, some parts of 
the United States have been investigated. Schweinitz § first 
made known to any extent the riches of this country, especially 
Carolina, and in this state the late Dr. Curtis and H. W. Ravenel 
continued their labours. With the exception of Lea’s collections 
in Cincinnati, Wright’s in Texas, and some contributions from 
Ohio, Alabama, Massachusetts, and New York, a great portion 
of this vast country is mycologically unknown. It is remarkably 
tich in fleshy fungi, not only in Agaricini, but also in Discomy- 
cectes, containing a large number of European forms, mostly
