GEOGRAPHICAL DISTRIBUTION. 281 



added considerably to the number of Dlscomycetes^ 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 ;t 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 

 rich in fleshy fungi, not only in Ayaricmi, but also in Discomy- 

 cctes, containing a large number of European forms, mostly
