among which were several of the new species recently described in the 
Torrey Bulletin. 
All mycologists who are familiar with the excellent specimens of 
Sydow’s “ Uredineen,” (published in Berlin), which has now reached 
its eighteenth fascicle, (900 specimens) will welcome the beginning of 
a new set by the same author devoted to the Ustilaginee. Fascicle I 
of this new set “ Ustilagineen,” containing fifty specimens appeared 
within a few months. 
We should not overlook here the two centuries of “ New York 
Fungi” published by C. L. Shear, heretofore noticed in this journal. 
The excellence of the specimens commends this collection, especially to 
those who are beginning the study of the larger fungi (Hymenomycete) 
to which it is mainly devoted. We understand that Century III is 
nearly ready for distribution. 
Nor must we omit the useful “ Economic Fungi” published by A. 
B. Seymour and F. S. Earle, of which seven fascicles (of about 50 
species each) have appeared. The work deserves to be successful. 
We do not know whether the “ Uredineæ Americane,” of which one 
fascicle was issued a year or so ago by M. A. Carleton, is to continue or 
not. It certainly made a good beginning. 
We may add to the fovopring the distribution of “ Canadian 
Lichens,” and “ Canadian Mosses” by John Macoun of the Canadian 
Geological Survey, which contain good specimens, neatly prepared and 
often of much interest on account of the region from which they 
were obtained. 
Verily the tribe of makers of exsiccati is a numerous one, and were 
we to include all those devoting themselves to supplying plants of 
particular regions, it would be increased three or four fold—CHARLES

Some Recent Botanical Papers.—Dr. T. F. Allen’s valuable 
work, ‘‘ The Characex of America,” has made progress by the issuance 
of another fascicle containing descriptions and illustrations of nine 
species of Nitella of which three are new to science. Too much praise 
can not be given to the industrious author, who for love of Science, 
brings out, from time to time, the successive parts of this first work ona 
group. hitherto little studied in this country. 
and Everhart have added a convenient Analytical Key to 
their North American Pyrenomycetes, which has hitherto lacked that 
useful portion. The same authors have recently distributed a reprint 
from the proceedings of the Academy of Natural Sciences of Phila-
