COLLEMACEM, 



Collema saturninum, Ach., infert. 



Fungi were not collected, except a few of the more solid ones, which have 

 not yet been determined. The softer species are very difficult to preserve 

 during such a journey, when travelling constantly upon water in birch-bark 

 canoes. 



To this first enumeration of the species of plants occurring about 

 Lake Superior, and which belong to the subalpine region as such, we 

 subjoin a list of species, which cannot strictly be referred to this one, 

 though they occur in it. They are few in number and still fewer 

 of them belong to the Cryptogamous plants.
