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 ssmewhat biatorine. i
