I have never seen this species in nature, and I have little to add to 

 the dates, given by Tii. Fkies Lieh. Scand. p. 55: 'ad rupes irrigatas in 



regionibus argillaceo-schistosis parce visus'.

The distribution of this species is insufficiently known in Norway. 

 It is evidently distributed throughout the whole country (lower than the limit 

 of the trees) as a 2- common species. Frequent near Kristiania, in Western 

 Norway it is 'common, especialh' at the l^jords' (Havaas). 



Fertile specimens are usually rare, and sterile plants easily confused 

 with Stereocaulon pilcatuiii. 



Moist rocks, as borders of rivers and brooks, and the like.
