The Mosses of Monroe County, Indiana, II. 



Mildred Nothnagel and F. L. Pickett. 



At the wiuter meeting of the Indiaua Academy of Science in 1912 the 

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

 pally of fall-fruitinu; 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 I'esult of that work and includes fourteen new species, among 

 ■^'hieh 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 Botanical Department of Indiana University. Full 

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

 the specimens, are on file 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 numbers in the herl)arium. 



In this list some species are included which were in the fiu-mer list. 

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

 of haldtat. and to show the herbarium numbers 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 

 examinntion may be of use. The dissections of leaves from different parts 

 of a i)lant 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 cai'efully 

 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. Siich mounts are very convenient 

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

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