Fig. 4. S. PARALLELA. 



THE furface of this is often nearly fmooth. The 

 fphaerules are more or lefs in number, imbedded in a 

 blackifli fiibfl:ance which rifes above the burit cuticle, 

 Handing in little parallel patches above it. 



Fig. 5. S. PicEA. 



THIS is irregular, and fmooth on the furface, refem- 

 bling dry pitch, partly bleached to a brownifh colour, 

 and cracked. The fphaerules are imbedded, but the 

 whole Fungus lies on the outlide of the wood on 

 which it grows. 



Fig. 6. S. convergens. 1'odeFung. Meckl. t. i^-Jig- m. 

 THIS fpecies rifes from the cortex in a peculiar 

 manner, limilar to a parcel of flafks, having 4, 5, 6, 

 or more together, preffing the cuticle in a convergent 

 manner upwards, and perforating it: their mouths are 

 juft feen through it. This fpecies can fcarcely be un- 

 derftood without cutting it in a tranfverfe direition. 



Fig. 7. S. OBLONGA. 

 THIS fpecies is fomewhat allied to the preceding, but 

 the cuticle is perforated in an oblong manner and 

 nearly tranfverfe direilion. The bafes of the fpheerules 

 are irregularly feated; their necks are converged, more 

 or lefs curved, and longer than the laft. 



Fig. 8. S. tuberculosa. With. &c. 

 THIS feems fometimes to form fphaerules round its 

 furface, at other times not. When without thofe 

 fphxrules it often exactly agrees with the external 

 appearance of L. piji forme ^ tab.i"]!. E. Fungi ; and 

 fometimes refembles a fmall S.fraxinea, tab, 160. 

 E. Fungi ; and we fufpeited L. acarifotme might alfo 

 belong to it. Some fpecimens the Rev. Mr. Francis 

 lately fent me confirm this, and he agrees with me. He 

 alfo thinks that my figure of L. radiatum is nearly 

 allied to it ; other friends have formed the fame con- 

 jecture. 



Fig. 9. S. irregularis. 



THIS Spharia is irregular two different ways. It 

 forms irregular tubercles of a brownifh black ; the 

 fubftance being of a reddifli brown, including fphae- 

 rules fcattered irregularly in it.
