 THIS one might imagine was the young of 5. decor- 

 ticans ; but as we have only found it in this Hate, that 

 is mere conje6ture. It fpreads upon the cortex under 

 the cuticle, is of a cinereous colour with white punc-

 holding a white fubftance.

 had not determined what to call it : therefore we have 

 placed it among the Sphacria^ although it may be nearly 

 allied to a Lichen. The little fphaerulae ftand on the 

 outfide, with a white ground which rifes round and 

 covers each fphcerule.
