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

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

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

 our specimens.

 upland and subalpine districts. Distr. Probably general in Great Britain; 

 apparently rare in S, Ireland. B. M. : Esher, Surrey ; Dartmoor, Devon-

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

 be confluent, though differing also in the subtruncate 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.
