npHIS is a fmall, black, oblong tubercle, the fize of a fmall 

 A flea; it is prominent, and has a deep furrow along the 

 back, from end to end, by which it feems as if cloven in two, 

 but the halves are joined together at the bafe. a. is the natural 

 fize of the plant; at b. it is magnified till the black pun&ures, 

 which indicate the fphaerulas underneath, are vilible; at c. it 

 is cut horizontally, and laid open, to mew the difpofition of 

 the' iphaerulas, or little fphasrical feed veflels ; at d. it is cut per- 

 pendicularly for the fame purpofe. The plant, under the 

 double magnifier, appeared like a bivalve fhell, when clofed 

 and fcen in front. 



Grows about Halifax, in feveral places, on twigs and 

 branches of am trees, when in decay. 



Poffibly the Lichens, fcriptus and hebraicus, may belong to 

 this Genus; but of this I have not made fufficient obfervation, 

 nor whether thefe two are only varieties of the above.
