Fig. 9. S. fuliginoss.
MOST common on rotten branches of oak. It spreads upon the surface of the cuticle, staining it black, or riling in irregular roughish tubercles, forming somewhat regular sphærulæ within, altogether having a very sooty appearance.
Fig. 10. S. diffusa.
AFTER throwing off the cuticle, it diffuses itself in different-formed patches on the surface of the cortex. The sphærulæ within are somewhat egg-shaped, acuminating towards the mouth.

THIS one might imagine was the young of 5. decorticans; but as we have only found it in this Hate, that is mere conjecture. It spreads upon the cortex under the cuticle, is of a cinereous colour with white punctures, which are the mouths of the little sphærulae holding a white substance.
Fig. 12. S. lichenoides.
THIS was sent me by the Rev. Mr. Relhan, who had not determined what to call it: therefore we have placed it among the Sphæriæ, although it may be nearly allied to a Lichen. The little sphaerulæ stand on the outside, with a white ground which rises round and covers each sphærulæ.

Fig. I. SPHÆRIA immersa.
THIS Sphæria penetrates the wood in various directions, but forms the sphærules on the outside.
Fig. 2. S. Populi.
NOT unfrequent on poplar leaves.
Fig. 3. S. ulmaria.
A COMMON inhabitant in the autumn of the dead leaves of Ulmus campestris.
