THE BRYOLOGIST 



Vol. IV. April, 1901. No. 2. 



In The Plant World for October, 3- 145-148. />/• 5. 1900, Mr. F. H. 

 Knovvlton has some " Notes for the Beginner in the Study of Mosses." We are 

 very glad to see others trying to interest people in the study of mosses, for ex- 

 perience has shown that persons so interested very soon subscribe for The Brv- 



OLOGIST. 



* 



Thk Editors of The Brvologist feel a personal loss in the death of Mr. 

 Thomas A. Williams, formerly editor of the Asa Gray Bulletin. Although Mr. 

 Williams had begun a series of articles on lichens in the Asa Gray Bulletin, he 

 had promised all the aid and assistance in his power to Mrs. Harris with her 

 articles in Thk Brvologist. By his death the botanical world loses not only a 

 scholar, but a man of rare courtesy and kindliness of nature. 



* 



We have added four extra pages to this issue in an attempt to bring the 

 descriptions of new species up to date. It is interesting to note that most of 

 our new species are by Eiiropeans, who seem to have greater assurance in matters 

 relating to American bryology than American botanists themselves.
