YORKSHIRE MOSSES. 



C. A. CHEETHAM. 



DiCRANODOXTIUM LONGIROSTRE B. & S. var. ALPINUM Schp. 



Whilst on a visit to Buckden last November, with Mr. A. R. 

 Sanderson, we found this moss in plenty, high up the hillside 

 where the woods and moors join. It is the Cainpylopns alpinus 

 of ' Lees' Flora,' and this will be a second locality for it, th:' 

 other being Tnglebro', where it occurs in sheets in the turf 

 on the south shoulder. 



Mr. A. Wilson, F.L.S., who' has found it in West Lancashire 

 on Greygarth and Thrushgill Fells, says that the additional 

 locality is very interesting, and he suggests that it may be found 

 on other high peat-covered fells. On the same occasion we 

 found the var. calvescens Hobk. of Hylocomium sqitarrostim 

 B. and S. 



DiCRANODONTIUM LONGIROSTRE B. and S. 



• This is the type of which the above is now considered a 

 variety. It occurs in shade in woods on humus, whilst the 

 variety is found in the open on turf or peat. In January last 

 I found this moss in Guy's Cliff Woods, Pateley Bridge, which 

 is a new drainage area for it, the previous records being : — 

 Wharfe, Bolton Woods, Dr. Wood (I gathered it here last Christ- 

 mas) ;Calder, Heptonstall, J. Nowell. 



Phascum Flgerkeaxum Web. and Mohr. 



On the occasion of the annual meeting at Doncaster last 

 D cember, I gathered this moss in Cusworth Park. It is an 

 additional species to the West Riding list. 



Barbula gracilis Schwseg. 



A moss which I found at Knaresbro' in May 1908, and which 

 I submitted to the Moss Club as B. Hornschtichiana Schultz, 

 has been determined to be the above species by Mr. W. E. 

 Nicholson and Mr. H. N. Dixon, F.L.S. This is also a new 

 species to the West Riding.
