Habit. In Eckero, insula Alandica, in littore maritimo prope 

 pagum Torp, 27/VI 1896, a me lectum. 



Bryo Marratii proximum a quo praesertim foliis latioribus, 

 saepius acuminatis, forma capsular et operculi differt. 



Arten har af Lektor Arnell senare blifvit funnen i Sverige 

 pa en lerig hafstrand i Hille, Gestriksland 1G /o98. De exemplar, 

 som af honom valvilligt tillsiindts mig, ofverenstamma temligen
