 Upon rocks in mountainous places both in thq 



Highlands and Lowlands frequent. 

 We fufpecl this not to be fpecifically different 



from the preceding. 

 The ftalks grow in clofe thick flufters, an inch or 

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

 lour, dichotomoufly branched, the fummits of 

 the branches bifid, fomelimes trifid, all of equal 

 height, and obtufe at the ends. Previous to 

 their fructification the (lalks grow thicker, 

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

 branches. ' y;. .. 

 The fruftifications are fimilar to thofc of the fore- 

 going. The figure of Ditlenius reprefents them 

 in their decay 'd ftate, half worn away, or as if 

 cut tranfvcrfely afunder, with a fine black pow- 

 j der in their centre. 

 li difi^ers chiefly from the preceding in its more 

 regular and dichotomous ramification, and the 

 fummits of the branches being' of equal height, 

 -* '^. not fo minutely divided, and rather obtufe. In 



i the frudification, and other refpeds, there is no 

 j* ijiaterial variation^
