306 BRYOLOGY OF NEW ZEALAND. 
horizontal or suberect, rather bright red, with a deep red, acutely 
conical lid. 
It is a frequent plant, and extends all over the Australasian 
region. 
RHAPHIDOSTEGIUM (Bry. eur. as subgenus) De Not. Cronaea ii, 31° 
(1867). 
A clearly marked genus, distinguished by the nerveless leaves, 
with enlarged, usually very distinct and inflated alar cells, an 
small capsule with a long, subulate or rostrate beak. The texture 
of the exothecium is also markedly different from that of most, at 
least, of the Hypnaceous mosses, the cells being short, wide, almost 
isodiametrical, and with the walls highly thickened at the angles. 
The infloreaceneé is important, but needs very careful examina- 
tion, as the ¢ flowers are unusually small. The species are difficult 
to distinguish, and have given rise to much confusion and uncer- 
tainty.
