Lichens. 



Next to Mosses and Seaweeds, the Lichens of the north 

 of Ireland occupied more attention early last century than 

 any other group of Cryptogams. Templeton formed a 

 large collection, which is referred to by Dr. Taylor in Flora 

 Hibernica, where the results of his researches in Ulster 

 are given. Later on, two well-known students of Lichens — 

 Admiral Jones and Dr. Maingay (the latter especially from 

 the neighbourhood of Ardglass) — made large additions to our 

 knowledge of the Lichens of the district. Dr. Moore also 

 collected a considerable number in Co. Antrim, including 

 some rare species. Nothing has been done in recent years 

 to add to our knowledge or bring it up to date, with the 

 exception of a small collection made by the Rev. H. W. Lett 

 in the Mourne Mountains. No very rare species are re- 

 corded, and the mountain group does not appear to be rich 

 in these plants, although not as yet sufficiently explored. 



The only species peculiar to Antrim or Down is Lecidea 

 Mooreana Carroll, found at Crow Glen, near Belfast, Co. 

 Antrim. Lecidea Templetoni Tayl., another rare species of 

 this genus, was first described from a locality near Belfast. 

 Cushendall and Sallagh Braes are the only Irish localities 

 for Solorina saccata. The Iceland Moss Cetraria islandica 

 has been found on Slieve Donard, its only other Irish locality 

 being Mangerton. It is strange that the " tree lungwort," 

 Sticta pu/monaria, one of the largest and commonest British 

 Lichens, though widely spread in Scotland, has not yet been 

 recorded from Ulster. No list has been published of the 

 Lichens of the north-east of Ireland, but localities are given
