Upon dry'd fticks, and the decay'd bark of trees, 

 XI— III. 



Thefe are hard convex tubercles, with an uneven 

 furface, of the fize of warts, and of a black 

 fufcous color. Whtn cut trariiverfely, their 

 internal parr appears to be full of minute hol- 

 low fpheerules, imbedded in a dark fufcous 

 fubftance, and replete with a bk ck povvder. 



The tubercles are comnionly diftin6t, but are 

 fometimes confluent. 



It has very little affinity with the Lyco-pcrd.ons. 

 We agree with Halkr^ that it ought to be 

 ranked under a new genus. 



The tubercles are fometimes found externally of 

 9 ferrugineous color.
