VOL. XVIII. (3) THE MOSSES OF GLOUCESTERSHIRE 265 



Seligeria pusilla B. and S. 33, 34. Common on rocks and 

 stones in woods on the Cottes wolds. Also found sparingly on 

 limestone rocks in the lower part of the Wye Valley. 



Seligeria calcarea B. and S. 33, 34. On shady walls and 

 old quarries in several places on the Cotteswolds. This species 

 is more at home on the Chalk, and does not thrive so well on 

 the Oolitic rocks. 



Seligeria recurvata B. and S. 34. On rocks at Symonds 

 Yat (Binstead and Miss Armitage) , and near the Devil's Pulpit 

 in the lower part of the Wye Valley. 



Ceratodon purpureus Brid. 33, 34. Generally distributed, 

 though not one of the common mosses of calcareous districts 

 like the Cotteswolds. 



Ceratodon conicus Lindb. 33. On mud-cap of walls on the 

 Cotteswolds. Near Bisley ; Poulton ; Fairford ; and Stow-on- 

 the-Wold. 



Cynodontium Bruntoni B. and S. 34. On Old Red Sand- 

 stone rocks and walls in the Forest of Dean. Near The Buck- 

 stone (Miss Armitage), and near Mitcheldean. Also recorded 

 by Thwaites in the Annals of Natural History, but this may 

 be a mistake, as there was no specimen in his herbarium. 



Dichodontium pellucidum Schp. 33, 34. On rocks by 

 streams, not uncommon in the Forest of Dean. Rare on the 

 Cotteswolds ; Woodchester (Reader) ; near Boxwell ; and in the 

 Slad Valley near Stroud. Usually sterile, c. fr. by R. Wye at 

 Symonds Yat (Miss Armitage). 



Dichodontium flavescens Lindb. 34. By stream near 

 Symonds Yat, barren (Nicholson). A specimen in Ley's 

 herbarium, from " Rill side Bicknor Walks," is, I think, D. 

 pellucidum. 



Dicranella - heteromalla Schp. 33, 34. Generally dis- 

 tributed, -but not one of the common mosses of the Cotteswolds. 

 Var. sericea Schp. (34) on sandstone rocks near Oxenhall ; near 

 Mitcheldean ; and the Hudnalls (near St Briavels) . Mr Ley in 

 his " Flora of Herefordshire," and in " The Botany of Mitchel- 

 dean District," records Dicranella secunda Lindb. from a sand- 

 pit near Mitcheldean. I have seen the specimen in his herbarium, 

 and the plant is a curious form of D. heteromalla. See 

 " Journal of Botany," 1912, p. 306.
