70. Bryum (Webera) subcucullatum, C. M. & Kindb.

It seems to be a good species, when the inflorescence is 

 paroecious. It was regarded by me (in Eur. and N. Amer. 

 Brvineae) as a subspecies of B. conimntatum.

 apex, yellowish (not red-) limbate; capsule less narrowed to the 

 mouth.

72. Bryum submicans. 



Allied to Bryum arcticum\ but capsules are less narrowed to

 oblong (not subglobose). Leaves longer, broadly (not narrowly) 

 limbate, the upper with long-excurrent costa. Pedicel of
