SEDBERQH DISTRICT LICHENS, 



Observed on the occasion of the August Meeting of the Yorkshire 

 Naturalists' Union. 



JOSEPH A. MARTINDALE. 



The district between Sedbergh and Cautley Spout is not very rich in 

 Lichens, though it may be taken as certain that with more time than 

 was at the disposal of the Botanical Section, a longer list of plants 

 could be prepared. Some of the walls near the town would doubt- 

 less repay careful search, but these were passed quickly by in order 

 to reach the ' Spout ' as soon as possible. Still, several Lichens 

 which might have been expected were not seen during the excursion, 

 although carefully looked for. Among these may be mentioned 

 Lecidea periplaca Nyl., which is abundant on slatestone walls to the 

 north of Kendal. The plants observed during the excursion are, 

 with few exceptions, those that are common in the Silurian districts 

 of South Westmorland.
