191 2. Knowlks — Notes on West Galway Licheiis. 33 



Besides the Cleggan, Ballynakill and High Island Lichens 

 there are several in the list which were gathered at Carna 

 and in the neighbourhood of Roundstone in July, 1910, but 

 held over as being too few to publish by themselves. Among 

 them are Usnea hirta and U. florida, corticolous species 

 which here, as on Clare Island, in the absence of trees, were 

 growing on rocks. 



Altogether from the various localities mentioned, there 

 are 48 species and 6 varieties new to Co. Galway (Ci of 

 Mr. Adams' list), Of these, 3 species and one variety are 

 new to Ireland. All the others on the list have had 

 previously either only a vague record from the district 

 such as " Connemara " or " Co. Galway " or they have 

 been known only from a single locality. 



In compiling the list I have followed the plan adopted 

 in the paper on the Clare Island Lichens, and used the 

 classification of Parts I. and II. of the " Monograph of 

 British Lichens." 



I owe many thanks to Miss Lorrain Smith for examining 

 several of the specimens and confirming my identifications, 

 and also to Mr. West for identifying Rivularia atra. 



The lichens new to Ci have an asterisk placed in front of 

 their names, while those new to Ireland have a dagger 

 prefixed.
