Leiicobryum minus. Under this name it appears that two species have been mixed up, and my 

 valued friend, Mrs. Britton, having examined all the types, has, with her usual 

 acuteness, cleared up the matter and kindly sent me the result. Of the two species 

 only one is found in Europe, but both in America. The former will stand as 

 Leucobryum albidum (BRID.) LINDB.
