Distinguished by the subjmlvinate thalhis, -which in its .smaller states 

 is often almost covered by the confluent soredia. With us it is never 

 seen fertile.

 maritime and upland tracts. — Distr. Local, though plentiful where it

The thallus is somewhat soft and often pliciform from rugosit}'. It 

 varies considerably in size as well as in the breadth and divisions of the 

 laciniae. The apothecia occur sparingly in this country, and the spermo- 

 gones, which are not frequent, are somewhat scattered, with spermatia 

 0,003-4 mm. long, scarcely 0,001 mm. thick. 



Hab. On the truuks of old trees, chiefly oaks, in wooded upland di.s- 

 tricts. — Distr. General and common in S. and W. England and S. and E.

Apparently distinct, with a simple, leaf-like thallus. It has the same 

 relation to ithe type as the analogous form of var. amplinta has to
