First found by the Rev. John Harriman. This Li- 

 chen, though widely dispersed over Europe, is rare 

 in England, nor does it appear to have been found 

 in Scotland by any Botanist but the late Mr. Dick- 

 son. In his Fasc. iii. 14, he gives no precise loca- 

 lity, but merely says " In rupibus Calcareis Scoti- 

 cis," with us it is confined to the Encrinal Limestone, 

 which it has the property of excavating in the same 

 way as Lecidea immersa, and some other Lichens that 

 grow on chalk and limestone. Its structure is so 

 peculiar that it might constitute a genus.
