In their earlier and more advanced stages of development, the 

 apothecia closely resemble those of G. exanthema tica, near which the 

 species might almost be placed. The British specimens are well 

 fertile, with the apothecia occasionally submoderate in size. 



Hah. On trunks of trees, chiefly elm, rarely ash, in maritime and 

 upland situations. — Distr. Only in S. England and the Channel 

 Islands, but plentiful where it occurs. — B. M. St. Brelade's Bay
