*This and all other Greenland species hereafter noted in this work were collected along 

 the western coast of Greenland from 1812-1886, mostly by the various expeditions sent out to 

 explore that country ; viz. The Nares Arct. Exp., 2d butch North Polar Exp., Hammer's 

 Exp., 'Danish Exp. 1876-79, Fylla Exp. 1884-86, etc., etc., and described by Prof. E. Rostrup in 

 his "Fungi Groeiilandise," published at Copenhagen in 1888,
