Fig. 6. S. asper. 



WE put this among the Spbtpria from its refem- 

 blance, although it feems deftitute of the common co- 

 vering of the genus. It burfts the cuticle in fo rough 

 a manner as to give the Itick it grows on the appear- 

 ance of a rafp or file. 



FjG. 7. S. MARGINATA. 



THE mouth of this Spharia perforates the cuticle, 

 and the edges turn back upon it, forming a broad 

 whitifh border : fometimes thefe have 2 or 3 perfora- 

 tions in them, and 2 or 3 mouths beneath. 



Fig. 8. S. subimmersa. 



ABOUT half of each fphasrule rifes, fwelling the 

 cuticle hemifpherically, and giving it a dark greyilh 

 tinge. 



Fig. 9. S. puNCTUM. 



THE fphserule is nearly round, buried in the upper 

 part of the cortex. The mouth perforates the cuticle, 

 and has round it a blackifh ftain. 



Fig. 10. S. EMERSA. 



THIS burfts through the cortex, forming a mouth 

 under the cuticle, with a fpreading black circle round 

 it, occafionally perforating the cuticle with a fmaller 

 circle or ftain round it. 



Fig. II. S. CRUSTACEA. 



THE cruftaceous cover of this Fungus fpreads on 

 the outfide of the wood, in parts forming little puf- 

 tulate fphserulas, with fomewhat pointed mouths.
