The thallus, which in the larger states expands from a centre, is with 

 us generally smoothish, seldom rugose. It is often covered with the 

 blackish efflorescent isidia, by which at once it may be distinguished 

 from the allied species. The apothecia, which are rare in Great Britain, 

 are at length sjmewhat biatoriue. 



Sab. On mossy trunks of old trees and on rocks in moist shady places, 

 especially by waterfalls, in upland districts. — Distr. General and not un-
