Report of the Curator pro-tem of the Hepatic Department 
Only 120 specimens have been added to the Hepatic Herbarium, making 
the number 5909. The collectors represented are the following: Geo. M. Pendle- 
ton, who found two additional stations for the rare Cephalozia aflinis in Cali- 
fornia; S. H. Burnham; J. M. Grant; J. Evans, Clevea hyalina from Washington; 
Geo. B. Kaiser gave two Southern species collected by Mrs. J. M. Fox; Rev. 
Demetrio gave two northern species collected by Prof. Macoun and Rev. Mueller; 
C. C. Haynes a small set of Pearson’s British Exsiccatse, etc. 
Capt. Conklin did not forget us, having sent an interesting looking set 
of French hepatics collected near Vichy; he being in charge of a ward in Base 
Hospital No. 1, located there. Mr. G. K. Merrill, who is sending us Maine 
hepatics, is heartily welcomed to our list of contributors. These specimens, 
together with various “left-overs,” are being slowly worked up and will be re- 
ported on next year. 
Prof. A. W. Evans has given eleven reprints from the Journal of Botany 
of W. S. Pearson’s descriptions and figures of British hepatics and his papers 
on the botanical works of Gottsche and Benjamin Carrington. The library 
connected with this Department is steadily increasing in size and importance. 
Gifts of reprints are requested from members.

Report of the Lichen Department for 1918 
During the past year four more fascicles of the Lichenes Exsiccati, dupli- 
cates from Dr. Hasse’s large collections, have been distributed. This makes 
in all ten fascicles of 25 specimens each, each species being described in Dr. 
Hasse’s “Lichen Flora of Southern California.” There remains on hand still 
enough material to make, perhaps, two more fascicles, thus completing three 
centuries. However, as but a slight amount of this material is described in 
the “Lichen Flora of Southern California,” and in the later articles in the Bry- 
ologist, it is considered wiser to delay the issue of further fascicles after number 
ten, until a more detailed report upon the material can be given. This last 
may take considerable time, but when completed all subscribers to the earlier 
sets will be notified. 
As stated in the Report for 1917, all the complete sets of the Exsiccati have 
been subscribed for. There is, however, much material, duplicating specimens 
issued in the sets, which can be sold in lots of 25, 50, or 100 specimens, upon
