Report of the Curator of the Moss Herbarium* 



The moss herbarium of the Sullivant Moss Society now contains 2,895 

 mounted specimens, which represent 970 species and varieties, belonging to 230 

 genera. During the past year 698 specimens have been mounted and these 

 specimens have added 221 species and varieties and 42 genera new to the her- 

 barium. 



Especial thanks for exceptionally valuable exchanges are due to: A. H. 

 Brinkman, I. Gyorffy, E. lishiba, David Lillie, and P. G. M. Rhodes. A set 

 of mosses from England and Switzerland contributed by H. H. Knight were 

 among the most generous and admirably collected specimens received during 

 the entire year. The collections of A. H. Brinkman in British Columbia have 

 also been most valuable and noteworthy. It is to be hoped that during the 

 ensuing year the same interest among these members may be continued and 

 even increased and that other members may be led to take more active part in 

 building up the herbarium. The curator is ever ready to make determinations 

 to the best of his ability and much excellent duplicate material is at hand to 

 exchange with those who will be kind enough to honor the herbarium with their 

 contributions.

Report of the Lichen Department* 



The herbarium has been enriched by many generous contributions during^ 

 the year. Special mention should be made of Mrs. Mary E. Williams, who pre-^ 

 sented us with nearly 200 specimens, collected in Maine, Massachusetts, New 

 York, Pennsylvania, North Carolina, South Carolina, Florida, Tennessee and 

 Lapland. 



There are now in the herbarium 1,859 specimens, representing 530 species 

 and varieties. 405 specimens have been added during the year, 65 being new 

 to the herbarium. 



During the summer the lichen herbarium has been rearranged according 

 to the classification of Engler and Prantl, which, of course, necessitated a change 

 in the generic and specific names of many of the specimens. The whole her- 

 barium of 1,859 specimens represents the work of about 125 collectors, and con- 

 tains lichens from nearly all parts of North America, from Europe, Asia, Australia, 

 and some of the islands of the Pacific. Africa and South America are not yet 

 represented. 



There are, to my certain knowledge, at least 63 present members of the 

 S. M. S. who have collected lichens, yet how few have offered even one species 

 in the Bryologist! Will not some of these collectors come forward during 1913
