SPH^RIA BIFRONS. 



Very common on the decayed leaves and flalks of 

 the Holly, Ilex aquifolium, but we believe it has hitherto 

 efcaped publication. We have called it bifrons, on 

 account of its having the fame appearance on either 

 fide of the leaf. It is nearly flat, rifing a little above 

 the difk of the leaf, and quite black. There are cot- 

 tony fibres penetrating the leaf from one fide to the 

 other. We could not detect any thing like feeds.

SPH^RIA CONCAVA. 



OOMEWHAT more common than the laft mentioned, 

 and readily to be diftinguiflied by its concave difk, 

 which only penetrates through the upper fide of the 

 Holly-leaf. It has an operculum or cover, which ap- 

 pears to be the cuticle or outer fkin of the leaf. It is 

 obfervable that the leaves of the Holly are compofed of 

 two fets of nerves as well as membranes, upper and 

 under, which in decay feparate.
