VOL. XVIII. (3) THE MOSSES OF GLOUCESTERSHIRE 275 



Trichostomum mutabile Bruch. 33, 34. Common on the 

 limestone of the Wye Valley, and of the Avon Gorge near 

 Bristol, where fruit is occasionally found. Rare on the 

 Cotteswolds. Rodborough Common, Stroud ; rocks in Wood, 

 Scotesquar Hill, near Stroud ; Cleeve Hill Common ; and bank 

 of the Windrush, near Seven Springs (near Bourton-on-the- 

 Water). Var. littorale Dixon (34) by the Avon, near Bristol. 

 Var. cofhocarfum Schp. (34) in several places in the Wye 

 Valley. 



Trichostomum tenuirostre Lindb. 34. On trees by R. 

 Frome, Stapleton (Thwaites). On rocks by stream near 

 Symonds Yat (Miss Armitage and Binstead). 



Trichostomum inclinatum Dixon. 33. On the Cottes- 

 wolds at Snowshill ; also at Cutsdean — an isolated part of 

 Worcestershire. Mr Dixon says that the Gloucestershire plant 

 agrees well with T. inclinatum, though, as fruit has never been 

 found in this country, there is some doubt as to whether this is 

 a British moss. 



Trichostomum nitidum Schp. 34. Plentiful on the lime- 

 stone of the Avon Gorge, near Bristol, and also of the Wye Valley. 



Trichostomum tortuosum Dixon. 33, 34. Common on 

 rocks and walls on the Cotteswolds, especially on or near the 

 escarpment ; also on limestone rocks near Bristol and in the 

 Forest of Dean. The fruit is found in many woods on the 

 Cotteswold escarpment, and also in the Wye Valley. A small 

 form of this moss with leaves straight when moist grows on 

 stony ground on Cleeve Hill. This moss grows in the form of 

 balls, quite unattached, on the stony slopes of Witcomb Wood 

 and elsewhere on the Cotteswolds. 



Pleurochaete squarrosa Lindb. 33, 34. On stony ground 

 in calcareous districts ; rare and usually found in small 

 quantity. Symonds Yat (Miss Armitage and Binstead) ; 

 quarries at Whittington ; Minchinhampton Common ; Stinch- 

 combe and Downham Hills, near Dursley ; Avon Gorge below 

 Durdham Down, Bristol. 



Cinclidotus Brebissoni Husnot. 33, 34. Common by 

 streams and rivers in the low ground. Fruit rare. On trees 

 by R. Frome, Stapleton, Bristol, c.fr. (Thwaites) ; Weston- 

 upon-Avon, c.fr. ; Carrant Brook, Beckford c.fr.
