I have never had any difficulty in distinguishing this spe- — 
cies from Br. cespiticium by the narrower, serrate leaves, and we 
their scarcely excurrent (sometimes not percurrent) nerve — 
On Barmby Moor the plants are closely tufted and send 
forth slender innovations about half an inch long, the leaves 
of which are smaller and proportionally broader than the 
stem-leaves, but all decidedly serrate upwards. Where the 
plants grow scattered, the leaves are longer, loosely set and 
spreading. Capsule pyriform, elongate; when mature, ofa 
scarlet hue. EA 
The only moss with which Br. erythrocarpon can be Co? 
founded, is a large variety of Br. atropurpureum, W. and M 7 
which has been found near Tonbridge Wells by Mr. Jenner, i 
and near Bristol by Mr. Thwaites. The latter may, how” 
ever, be distinguished by the following characters. 
leaves, though narrow, have a decided acumination ; they? 
quite entire or faintly denticulate near the apex, and 
nerve is considerably excurrent. The pedicel is more 0 ) 
The capsule is regular (mostly slightly curved inwards 
Br. erythrocarpon), and, though unusually elongated, © 
collum, sporangium, and operculum, are all ventricose. ^ 
operculum is larger, and terminated by a scarcely 1 
umbo; but in Br. erythrocarpon there is always an ap. 
which sometimes equals the rest of thelid. The inner p^ 
tome is white, and contrasts strongly with the deep 
red of the outer paries of the capsule. :
