RHACOMITRIUM SUDETIGUM, A MOSS NEW TO WORCESTER 

 COUNTY, MASSACHUSETTS 



Rachel L. Lowe 



Last winter a collection of mosses was given to our local museum, and I had 

 the pleasure of looking them over for old friends and new. Among the mosses 

 was one that looked like Hedwigia and still just enough unlike it to arouse suspi- 

 cion. Microsopical examination proved it to be Rhacomitrium Sudeticum 

 (Funck.) B. & S., a species new to Worcester County as far as known. ^ 



^For references to the distribution of the moss in various other parts of New England see the
