Obituary. — The death of Professor William A. Kellerman, head of the 
department of botany of the Ohio State University, on March 8, 1908, will 
be a shock to many of our readers. He was with several student assistants 
on his fourth winter expedition to Gautemala, in the interests of fungi col- 
lection. He was born in Ashville, Ohio. May 1, 1850, was graduated from 
Cornell University in 1874, received the degree of Ph. D. from the University 
of Zurich in 1881, was professor of botany in the Kansas State Agricultural 
College from 1883 to 1891, since then has been professor of botany in the 
Ohio State University. He established in 1885, in association with J. B. 
Ellis and B. M. Everhart, “The Journal of Mycology.” He was also the 
author of a textbook under the title of “Elements of Botany;” an “Analyti- 
cal Flora of Kansas ” (with Mrs. Kellerman); a “ Catalogue of Ohio Plants’’ 
(with W. C. Werner), and a large number of short articles involving a wide 
range of botanical activity. Professor Kellerman was a member of the Tor- 
rey Botanical Club, and known to many of the Chapter members and sub- 
scribers of The Bryologist by correspondence at least. He was buried in 
Gautamala.

It is reported that by the first of April, 1909, at the very latest, the large 
Sphagnum collection of Carl Warnstorf will be placed on sale. This col- 
lection, which contains at a conservative estimate about 30,000 specimens 
from all over the world, with unusually copious notes and annotations, is with- 
out doubt the most extensive and valuable peat moss herbarium in the 
world. Intending purchasers should place themselves in communication 
before the first of October, 1908, with Carl Warnstorf, Ringstrasse 55, 
Friedenau, Berlin, Germany.
