The locality is not given, but he says, ''Common on 

 trees." It is not common now; eighty -three years 

 have seen some wonderful changes in the county of 

 Durham. One, a fine specimen, is from Swartz, the 

 other seems to have been gathered about Castle Eden 

 Dene. 



127-128. Lecanoea salicina=: Lecanora aurantiaca, forma mi- 

 crothelia (Ach.), Johns. Two beautiful specimens ; 

 both from the county of Durham. 



I also found this form recently in the "Wansbeck 

 Valley. This is the first record of it for Great Britain. 

 The thallus is granuloso-conglomerate, distinctly 

 papulate or globoso-verrucose, and areolato-diffract. 

 The apothecia spring out of the verrucse, often 

 crowded, margin thick, paler, flexuose. 



129-130, Lecidea c^sio-etifa = Lecanora ferruginea^ forma 

 genuina (Korb.) Two specimens. One from Mary- 

 port, Cumberland; the other, a corticulous form,
