 variously incrassated thailus, whicli are also found in the Færoes, 

 mostly at Tliorshavn. Lecanora helicopis Wahlenb., L. subfusca 

 var. lainea Fr. and L. prosechoides Nyl. are — no doubt riglitly — 

 regarded as synonyms by Nyl. himself in Crombie's »Lichens of 

 Britain« p. 426 and the tj^pe must then retain its original name. It 

 was found by Mr. Borgesen. L. polioplmea Wahlenh. is found on 

 several of the islands (R., !) and is related to the three above 

 by a series of intermediate forms.
