Dr. A. W. Evans gave Plagiochila Smallii and Cheilolejeunea decidua. In A. 

 H. Brinkman's collection we found Marsupella sparsifolia and the writer con- 

 tributed Fossombronia cristula. The list therefore of N. A. species which were 

 wanted, has been reduced from no to 77. May we not hope for a still larger 

 response from the members who are interested in Hepatic during the coming 

 year? 



Other contributors to the herbarium were Roy Latham, H. Dupret, Mrs 

 M. W. Satchwell, A. J. Dradisman, Mr. Palmer, John L. Sheldon, C. A. Mosier, 

 E. C. Wurzlow, and R. S. Williams. 



Stewart Burnham gave 21 specimens from N. Y.; A. Lorenz, 21 from New 

 England; A. S. Foster, 19 from Washington State; O. E. Jennings, 24 from On- 

 tario; and the writer, additions from the Duluth-Superior District. 



This shows to some extent the range of distribution of the specimens sub- 

 mitted. The total number of specimens in the herbarium now numbers 4,334.

Report of the Lichen Department for 1915 



Thanks to the faithfulness with which Dr. Hasse kept his records, your 

 present Curator had very little trouble making out his report. 



During the past year 256 specimens have been added to the Lichen Her- 

 barium of the SuUivant Moss Society. The number of specimens now mounted 

 is 3073, representing 855 species and varieties belonging to 119 genera. 



Our list of contributors is headed by Mr. S. Rapp, that indefatigable worker 

 and collector, who sent more than 100 specimens. Other contributors were: 

 Prof. O. E. Jennings, who sent a fine collection from Ontario, collected by him- 

 self and Grace K. Jennings; Mr. J. M. Grant, who sent specimens collected in 

 the Olympic Mts., Washington; Mr. N. L. T. Nelson, who sent specimens from 

 Florida; Dr. H. E. Hasse; Dr. R. H. Howe, Jr.; and Mr. Roy Latham. The 

 European war is possibly responsible for our not having any contributors from 

 that part of the world, this year. 



Dr. Hasse, in one of his reports of this department, remarks "that in col- 

 lecting (material for the lichen department) only complete, well developed, 

 representative, and when possible, fruiting specimens, should be selected," and 

 he might have added, that wherever material is to be sent for determination, 

 by all means send ample material. 



It is to be hoped that the interest and the enthusiasm shown in the study 

 of Lichens in previous years will continue unabated.
