authors is not this, but a variety of the following species.—Brit. 
Exs.: Mudd, Clad. n. 76 (juvenilis). 
From the preceding this is distinguished by its different habit, the 
colour of the more corticate podetia, and the incurved margin of the 
scyphi. It is often somewhat macrophyllous at the base. The podetia, 
which are 1-2 in. long, not unfrequeutly arise from the margins or the 
surface of the leaflets, and are either naked or with a few smaller and 
scattered leaflets chiefly towards the base or at the apices. In sterile 
specimens they are often cornute or subulate, With us the apothecia 
are rare,
