THIS is remarkable for forming holes in the wood 

 on which it grows. It is fomewhat woolly on the 

 under fide. The whole Fungus is black. 



Fig. to and 11. P. erecta. 



THIS is a very variable Fungus. We can trace it 

 by degrees to F. fcutellata. It is fometimes deftitute of 

 hairs, fometimes has cHice only, or is without cilia., 

 with hairs at the back and underneath ; fometimes it 

 has both cilia, and hairs. It is oblong and upright, 

 fometimes lliort and clumfy, often fpreading. It varies 

 from a deep red to a greenifli yellow and a pale yel- 

 low, and is found on very wet mofs in damp places. 



Fig. 12. P. RiMOSA. 



WE are obliged for this, as for many other fpeci- 

 mens to the Rev. Mr. Alderfon, who obferved it on 

 brown paper on a beer barrel in his cellar. It is white 

 and cartilaginous, but when old is apt to crack in 

 the centre.

Fig. I. SPH^RIA minutissima. 



1 HIS minute Fungus, which is not to be feen without 

 a magnifier, appears, as far as we can determine, to be 

 a Sphceria. 



Fig. 2. S. POTENTILLiE. 



MANY plants bear the fame fpecies of Spharia in 

 common, but this feems to differ from all others. We 

 have only feen it on Potentilla verna., lying upon the 

 furface of the leaf. 



Fig. 3. S. ToFiELDi^. 



THIS differs from the laft in being immerfed in the 

 leaf of Tqfieldia palujlris. 



Fig. 4. S. pusTULATA. 



IN the cuticle of fome trees this forms a flattifh 

 puftule. 



Fig. 5. S. CoRNi. 



THIS Spbaria is found on Cornus Juecica. It lies 

 under the cuticle, but ftains it black, fo as to make 

 it appear as the upper furface of itfelf.
