in the list. Only Monroe County mosses are included in the present report, 

 but it is hoped that there will be time and opportunity to later extend the 

 list to include at least all the common mosses of Indiana. 



In general it may be said that the past season has been unusually 

 favorable for the gro\A-th and de\ elopment of mosses, and as a result it has 

 been possible to collect some very interesting forms. Among these should 

 l)e mentioned Aiioinodon attenuatus with rcgulai'Iy pinnate to plumose 

 habit due to .strong secondary growth from lateral buds, the formation in 

 fall of a second croi> of spores by such siiring fruiting forms as ("am]iyliuni 

 clii'ysonliylhiiu. Funaria tlavicaiis. F. liygronietrica and Weisia viriduhi. 

 and the presence of a fairly alnuidant supply of spore cases on sut-h rare- 

 fiuiting forms as T>eucobryum glaucum, Plagiothecium deplanatnm and 

 Thuidium delicatulum. 



The work of identifying mosses is tedious and time consimiing, and in 

 the main re<piires much careful ohservation with the use of a good com- 

 jinund microscope. The writer has found that (aily after the colle<-tor is 

 (piite well acquainted with group characters can he do any satisfactory 

 work without a good microscope. The most heljiful work on classification 

 is A. J. (Trout's "Mosses with a Hand-lens and iNIicros'-opo." with its usable 

 keys, distinctive descriptions and splendid illustrations. The older man- 

 ual of Lesquersux and James is often of value for descriptions of varie- 

 ties and of rarer forms not described in Grout's work. In jtreparing tin' 

 list the arrangement and nomenclature of Grinit have been used. Specially 

 difficult specimens have been referred to Dr. Grout for identification, and 

 liis name appears in connection with such.
