The thallus, occasionally little developed, varies somewhat in 

 thickness, and when dry is often tawny-greenish. It is usuallj- well 

 fertile ; the apothecia are very variable in colour in different 

 specimens ; the spores are often curved to an S-shape. The sper- 

 mogones are frequent with curved spermatia, 0,0025-30 mm. long, 

 0,0006 mm. thick. 



Hab, On rocks and boulders, at times inundated, in maritime and 

 upland tracts, occasionally on moist wood. — Distr. Seen only from a 

 few localities in Great Britain and Ireland ; no doubt often over- 

 looked. — B. M. Malpas, near Truro, and Mt. Edgecumbe, Cornwall ;
