Withdrawals, combinations, and early mistakes during the past ten years, have 
been 56 in number. This fact accounts for the discrepancy in the previous 
yearly reports and the actual recount.

Report of the Lichen Department for 1913 
It is gratifying to note the increase shown in the study of Lichens, evinced 
not only by generous contributions to the herbarium, but also by the number 
of un-named specimens sent in for determination. These requests have been 
conscientiously and as promptly as possible complied with. The stock of du- 
plicates on hand has assumed a quite respectable proportion, containing species 
from North America, the British Islands, and Australia. These are available 
to members desirous of adding to their private herbaria or, by way of exchange, 
with anyone for desirable forms not represented in the S. M. S. Herbarium. 
The Society’s Lichen Herbarium now contains 2,598 mounted specimens, 
representing 105 genera and 705 species, varieties, and forms. These ac- 
cessions are due to the generosity of members abroad and in this country, and 
though encouraging, yet, considering the number devoted to the study of Lichens,, 
a still better showing might be looked for.

Report of the Curator of the Moss Herbarium for 1913 
During the past year 565 specimens have been mounted in the Moss Her- 
barium of the Sullivant Moss Society, adding 23 genera and 175 species and vari- 
eties new to the herbarium, which now contains 3,460 specimens, representing 
1,145 species and varieties, belonging to 253 genera. 
Fine collections from British Columbia have been sent by A. LI. Brinkman, 
while valuable contributions to the herbarium from foreign sources have been. 
made by E. Corti, Max Fleischer, I. Hagen, E. Iishiba, D. A. Jones, Moncke- 
meyer, P. G. M. Rhodes, and I. Theriot. 
Among our home members who have been active are: F. S. Beattie, S. H. 
Burnham, W. W. Calkins, W. S. Cooper, Frank Dobbin, H. Dupret, D. L. Dutton, 
A. S. Foster, S. C. Hood, Mrs. E. L. Horr, H. S. Jewett, G. M. Pendleton, and 
S. Rapp. It is always the endeavor of the Curator to send out generous ex- 
changes, and work of determination is earnestly solicited. There would be more 
offerings if more members took advantage of them. May the ensuing year 
show renewed interest. Greater co-operation on the part of all our members; 
would soon show notable results.
