A list of Illinois mosses, published in 1878 by Sail and Wolf in Bulletin II. of Illinois State 

 Laboratory, contains 50 genera and 163 species. No doubt there will be found more, although the 

 nature of the country, the little difference in elevation and soil, and the lack of coniferous forests is 

 not favorable to moss growth.

 but a greater part may occur. These are the following: Ephemerum crassinervium Hampe, Sphaer-
