The states monophylla and congregata grow together in some abundance on the 

 Wrekin and adjoining hills, and may be seen passing into each other by every 

 degree of gradation.

 superficial cracks.

" Thallus somewhat thicker than in f. monophylla, simple or more or less com- 

 pound ; upper surface marked with a few superficial undulating indented lines, 

 the edges of which occasionally separate so as to leave a smooth black interstice, 

 under surface as in monophylla but more commonly blotched with the paler 

 colour of the upper side. — Lich. Brit. 



This state seems apparently a transition to hyperborea.

 lacero-lobate.

The mode of division of the margins of this state is different from that of the 

 preceding ones, and assimilates to that observable in anthracina.

 clustered or squamigerous, thin, unequally lobed, edges sometimes 

 ragged and erose, upper surface clotted and rough with sooty gran-
