The inflorescence of this species is truly dioicous *, and from the 

 circumstance oi female plants alone being found in the W. Pyrenees, 

 and only male plants in the Central, it may readily be conjectured that 

 no fruit was observed.

In the Pyrenees I never observed this species but on rotten wood, 

 but in Dec. 1847 I met with it on soft sandstone in Arncliffe "Wood, 

 Eskdale. All the other British specimens I have seen belong to the 

 following species.
