for the various subdivisions of botanical science. The first number has ap- 
peared, dated September, 1918, and it is planned to issue two volumes of three 
hundred pages each per year, at six dollars per year, the publisher being the 
Williams & Wilkins Company, Baltimore, Md. Heretofore our main reliance 
for botanical abstracts, which, of course, must be international, has been the 
Botanisches Centralblatt, and it is a distinct pleasure to call to the attention of 
our readers such a publication in English. This is a young journal and there 
will be up-hill work for its sponsors for a time. We would earnestly urge our 
readers to support the enterprise in every way possible. The first number in 
its 36 pages contains 206 abstracts ranging from mere citations up to some of 
more than four hundred words. 
A New Genus and Species of the Collemaceae. — Bruce Fink 7 finds that 
much of the lichen formerly identified as Collema pulposum (Bernh.) Ach., from 
stations ranging from the Atlantic to beyond the Mississippi, represents a new 
genus and species, Collemodes Bachmanianum Fink. In the Collemae the tricho- 
gyne extends beyond the surface of the thallus, and the small spermatia escape 
from the superficial spermogonia and are carried to this exposed portion of the 
female reproductive tract. In Collemodes, however, the spermatic are internal, 
much larger, 6-14 by 2-3 microns, not contained in spermagonia, and the tricho- 
gynes grow to the spermatia within the thallus. Identified from N. Y., Ohio, 
Mo., Iowa, Minn., and Wis. O. E. J. 
Uganda Mosses Collected by R. Duemmer and Others. — H. N. Dixon 
has identified and figured some Uganda mosses, principally specimens in the 
U. S. National Museum collected by Duemmer 8 The altitudes given are mostly 
4000 ft., a few being at 3500 ft. The species are: Trematodon intermedins Welw. 
& Dub.; Octoblepharum albidum (L.) Hedw. ; Fissidens subglaucissimus Broth.; 
F. erosulus (C. M.) Par.; F. sciophyllus Mitt.; Torlula erubescens (C. M.) Broth.; 
Schlotheimia Grevilleana Mitt.; Rhodobryum roseum (Weis.) Limpr. ; Neckeropsis 
truncata (P. Beauv.) Fleisch.; N. Lepineana (Mont.) Fleisch.; Porotrichum
