The Scapaniae have been the most interesting species to stud/ 
in the Duluth-Superior District. 
S. apiculata grows on hare moist wood not too old, in a 
spreading layer, usually gemmiperous and conspicuously alone. 
It was collected at Spirit Lake however in a thin mat, covering 
an old log, much mixed with mosses and Harpanthus scutatvs . 
In this instance the plants were crowded and upright and had 
much enlarged upper leaves on the fruiting branches. 
S. curia is verv common in the rock crevices of all the streams 
cutting the hTorth Shore and Copper Ranges. It also occurs on 
wood in the old swamps adjacent to Superior and on old logs
