The curator has accepted a commission in the Medical Officers Reserve 
Corps. While he is in army service, Miss C. C. Haynes of Highlands, New 
Jersey, has consented to take charge of the hepatic department. Contributions 
and all correspondence relative to hepatics should be sent to her address. 
Some unfinished business will necessarily be left till after the war. 
The curator wishes here to express his heartfelt appreciation of the fine 
courtesy in the friendships brought into his life by his association with the mem- 
bers of the Sullivant Moss Society.

Report of the Lichen Department for 1917 
As proposed in the report for 1916, the Lichen Department has distributed 
during the year four fascicles of Lichenes Exsiccati, these being duplicates of Dr. 
Hasse’s large collections. During the coming year we plan to distribute again 
the same number of fascicles, and, as in 1917, one fascicle in March, one in June, 
one in September, and one in December. A representation of the specimens 
offered has been added to the herbarium, which now numbers 3260 specimens. 
The sets of specimens offered to subscribers have all been taken. The 
Curator will now be pleased to hear from such members as have wanted to buy 
specimens in lots of twenty-five, fifty, or one hundred. All members more or 
less interested in lichens should take advantage of this offer. A nucleus of one 
hundred specimens will be an incentive to the further study of this interesting 
class of plants. 
During the year more of the original packages of material have been looked 
over, and, in all probability, it will be possible to issue three centuries of speci- 
mens. It is hoped that in the coming year all of the material will have been 
sorted, after which a complete report will be given. 
We have been remembered by a number of our members, to all of whom 
we here express our thanks and appreciation. Some have sent specimens for 
the herbarium; some have contributed to our exchange department; Miss Alina 
G. Stokey sent specimens from Massachusetts; Mrs. M. A. Noble, some from 
Florida; Mr. E. C. Wurzlow, some from Louisiana; Miss Helen E. Greenwood, 
some from Maine; Mr. B. O. Wolden, although not yet a member, some from 
Iowa; and Dr. O. E. Jennings, some from his part of the country.' Besides 
sending specimens for the herbarium, the following members contributed to 
our exchange department: Dr. Albert C. Herre, Mr. Severin Rapp, Dr. Wm. H. 
Weigmann, and Mr. Roy Latham. A hurried note from Mr. Latham tells of
