Larger than the type, usually 3-4 in. in length, with the podetia 

 softer, thicker, more open at the axils, and subfdstigiate at the apices, 

 which are somewhat variable in form. The apothecia are very rare in 

 our specimens.

Perhaps a more turgid state of the preceding, with which it seems to 

 be confluent, though differing also in the subtruucate apices. The podetia, 

 which are 2-3 in. in height and often more than 3 mm. in thickness, are 

 sometimes much deformed. In our British specimens the apothecia are 

 rare.
