(Fig. 7, VII). Two or three receptacles may be formed in succession. 
Often only a single archegonium is produced, occasionally two, so 
that in the mature state the receptacle has a single involucre (Fig. 7, 
111) or sometimes two involucres each containing a single sporo- 
gonium (Fig. 7, I). Later on the receptacle is raised on a stalk, but 
longitudinal section of thallus, x 50. V, two stomata, x 200. VI, scale from 
ventral surface, chloroplasts not shown, x 50. VII, scale from young female 
receptacle, x 50. VIII, horizontal section of involucre with a nearly ripe 
sporogonium, x 50. IX, spore, x 200. X, elater-like cells from apex of 
capsule, x 200. 
only if the archegonium is fertilised. The scales also are carried 
upwards and are found at the base of the ripe receptacle. There is 
no proper tissue of the receptacle at all. The bilabiate involucres 
are directed upwards and their walls have spaces which open by

(Fig. 7, VIII). The peduncle is about 5 or 6 mm. long, cylindrical
