LICHENES 



J. s. DE IC HM ANN BRANTH. 



THE order and nomenclature of the following list is much the 

 same as in Rostrup's »Færoernes Flora« 1870 ^ In the nnme- 

 rons cases where I can neither accept the conventional nor the new 

 species as true species — i. e. as distinct and not transitional - 

 but must regard them as confluent, they are marked with either of 

 the letters (a, b, c, d, etc.) in parentheses and placed after the number, 

 much in the same way as in Tuckerman's »Synopsis of the North 

 American Lichens, 1882«, so that the letter (a) placed in front of 

 a species generally indicates that the species is considered as the 

 principal or normal one. Many of the original specimens of the 

 lichens collected and enumerated by Dr. Rostrup were not to be 

 had for examination and some were but in an indeterminable state. 

 This evident drawback has however been diminished by the faet 

 of the Dr.'s Nylander and Th. Fries having revised the determinations 

 of many of the critical forms before the publication of Dr. Rostrup's 

 list. An R. within parentheses placed after the name of a locality 

 signifies that it is taken from the above-mentioned list by Dr. Rostrup ; 

 .' within parentheses indicates that the localities are those mentioned 

 in the collections of Mr. J. Hartz and Mr. C. H. Ostenfeld; some 

 material — marine species — has been collected by Mr. Borgesen 

 and one species (marked C. J.) was found by Mr. C. Jensen. In 

 »Botaniska Notiser«, 1896 p. 74 Simmons has recorded a few 

 lichens from the Færoes.
