From the preceding this is distinguished by its different habit, the 

 colour ot the more corticate podetia, and the incurved margin of the 

 scyyhi. It is often somewhat macrophyllous at the base. The podetia, 

 which are 1-2 in. long, not unfiequeutly 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 ba.-e or at the apices. In sterile 

 specimens they are often coruute or subulate. "With us the apothecia 

 are rare.
