being in straight lines. The calyptra while immature is very similar in both, but 

 while in the present species it remains erect and becomes many-lobed at the base, in 

 the Funaria it becomes oblique, the basal part remaining inflated and entire except 

 for a single lateral fissure. 



61. FUNARIA Schreb. 



Short-stemmed plants, resembling Physcomitrium in the 

 vegetative part ; leaves rather wide, with large cells. Calyptra 

 inflated at base, covering most of the mature fruit, finally 

 oblique, cucullate, otherwise entire at base, yellowish. Capsule 

 pyriform, erect and symmetrical or oblique and curved. Lid 

 plano-convex, rarely distinctly apiculate, the cells arranged in 

 somewhat spiral lines from the centre to the circumference. 

 Peristome none, single or double ; outer teeth 16, often twisted 

 obliquely to the left, sometimes united at their tips ; inner 

 peristome when present of 16 processes opposite the teeth, without 

 a basal membrane . Autoicous in all the British species ; male 

 flower discoid, terminal on a lateral branch. 



The species included in the section Entosthodon, here united, 

 following Braithwaite and Lindberg, with Funaria, have been 

 tossed about from one genus to another; but clearly there is 

 nothing gained by splitting up the genus, since any distinction 

 based on the peristome separates species allied by the form of the 

 capsule, and vice versa; on the other hand the affinity with 

 Physcomitrium is very close and the question seems rather to be 

 whether even that is rightly kept separate from Funaria ; here 

 however we have a real distinction in the calyptra, and a 

 consistency, at least in the former genus, in the form of capsule 

 and absence of peristome.
