"We fufped this not to be fpecifically different 

 from the preceding. 



The ftalks grow in clofe thick clullers, an inch or 

 an inch and a half high, of a grey glaucous co- 

 lour, dichotomoufly branched, the fummits of 

 the branches bifid, fomxtimes trifid, all of equal 

 height, and obtufe at the ends. Previous to 

 their fiudification the ftalks grow thicker, 

 wider, comprefs'd, pitted, and more naked of 

 branches. 



The frudlifications are fimilar to thofc of the fore-

 in their decav'd ftatc, half worn away, or as if 

 qut tranfverfely afunder, with a fine black pow- 

 der in their centre. 



It dlfl?ers chiefly from the preceding in its more 

 re"-ular and dichotomous ramification, and the 

 fummits of the branches being of equal height, 

 not fo minutely divided, and rather obtufe. In 

 the frudlificatioa, and other refpecls, there is no 

 material variationo
