The Mosses of Monroe County, Indiana, II. 



Mildred Nothnagel and F. L. Pickett. 



At the winter meeting of tlie Indiana Academy of Science in 1912 the 

 authors presented a list of tlie mosses of Monroe County, made up princi- 

 pally of fall-fruiting forms. That list appears in the Proceedings for 1912, 

 pp. 69-75. In the spring of 1913 the collection and identification of the 

 mosses in the neighborhood of Bloomington was resumed. The following 

 list is the result of that work and includes fourteen new species, among 

 which are representatives of one family and three genera not represented 

 in the previous list. 



Material has been prepared, as described in the former paper, and left 

 in the herbarium of the Tiotanical Deportment of Indiana University. Full 

 notes of habitat, time and locality of collection, as well as of condition of 

 the specimens, are on tile to make the material of value for comparison. In 

 this, as in the previous list, the numbers in parenthesis after each specie in- 

 dicate the accession numljers in the herbarium. 



In this list some species are included which were in the former list. 

 This has been done to indicate noteworthy differences in time of fruiting, or 

 of hal)itat, and to show the herbarium numliers of such species as were not 

 given numbers in the first list. 



To those interested in making permanent collections, the following plan 

 for preparing microscopic slides of species for convenient reference and 

 examination may be of use. Tlie dissections of leaves from different parts 

 of a plant as well as peristome, operculum and calyptra, are mounted in a 

 10 per cent, glycerin solution in water for examination. If satisfactory, the 

 slide, with the specimens well covered with the dilute glycerin, is carefully 

 protected from the dust until the glycerin is concentrated. Then a cover 

 glass on which a small piece of glycerin-jelly has been melted is carefully 

 placed on the previously warmed slide. Such mounts are very convenient 

 for quick reference, and are quite firm if covers at least 22 mm. by 32 mm. 

 are used. In the writers" collections the quick reference to such prepara-
