Though not found hj myself in Iceland, about 45 per cent, of 

 the foregoing lichens occur in my Norwegian collection. Of the 

 total of 83 species and varieties collected by myself, 53 (or 63 per 

 cent.) are not mentioned in my ' Flora,' and arc presumably, there- 

 fore, new to the Lichen-flora of Iceland, though they are for the 

 most part more or less common in ScandinaTia and Northern 



Europe generally. 



The ouly lists of Fiiroese lichens with which I am acquainted are 

 tjjose of Laudtf and Sir Walter Trevelyan+. The whole of the 

 licliens enumerated by Landt amount only to 2i; some of these are 

 merely varieties of other species ; all are classed under the old 

 and comprehensive genus Lichen. The foUowiug were not found 

 V myself, though they occur in Landt's catalogue :

"• ^pliceropJioron coralloides, Pers. 



* 45 species (including cases wlicre the type is represented only by a variety). 

 7 varieties and forms in addition to the type.
