Fig. 5. S. Heder^. 



THIS generally rifes through the cuticle of the leaf 

 in a fomewhat conical form. 



Fig. 6. S. betulina. 



THIS feems to fwell the cuticle, forming an oblong 

 black, fpeck. on the furface, and a woolly ferruginous 

 margin.

Fig. I. SPHv^RIA salicina. 



X HIS differs but little from the S. Lauri, t. yji-Jig. 4, 

 and ought to follow it. The mouth on the upper fide 

 of the leaf has a fmaller covering, and the bottom of 

 the fphaerule by its peculiar conlfru6tion, after pene- 

 trating the leaf, forms a black circle, fometimes with 

 a black dot in the middle. 



Fig. 2. S. PERFORATA. 



THIS forms roundifli holes through the cuticle of 

 the fticks on which it is found, iffuing from the cortex 

 either iingle or in bundles, with their mouths a little 

 beneath the holes. 



Fig. 3. S. ELLiPsosPERMA ? Bull. 492. Jig. 3. 



THE feeds were fo conglutinated together in our 

 fpecimens, that we could not politively difcern their 

 elliptic forms, though we were almoft confident they 

 were of that figure. 



Fig. 4. iS. EOMBARDICA. Bolt. 



A VERY common Spkaria, often fpreading over old 

 llumps of trees ; and often one over another, not un- 

 aptly refembling grains of gun-powder. In the young 

 liate, a white powder iffues from the mouths, after- 

 wards a black jelly or powder, till at length they be- 

 come empty fphaerules. 



FjG. 5. S. CORTICIS. 



THIS Fungus reaches entirely through the cortex. 

 The mouth perforating the cuticle fwells it a very little, 

 and fometimes a ftain appears round it.
