Fig. 9. P, immersa.
THIS is remarkable for forming holes in the wood on which it grows. It is somewhat woolly on the under side. The whole Fungus is black.
Fig. 10 and 11. P. erecta.
THIS is a very variable Fungus. We can trace it by degrees to P. scutellata. It is sometimes destitute of hairs, sometimes has cilliæ only, or is without ciliæ., with hairs at the back and underneath; sometimes it has both ciliæ, and hairs. It is oblong and upright, sometimes short and clumsy, often spreading. It varies from a deep red to a greenish yellow and a pale yellow, and is found on very wet moss in damp places.
Fig. 12. P. Rimosa.
WE are obliged for this, as for many other fpecimens 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.
TAB. CCCLXX.
Fig. I. SPHÆRIA minutissima.
This minute Fungus, which is not to be seen without a magnifier, appears, as far as we can determine, to be a Sphæria.
Fig. 2. S. Potentillæ
MANY plants bear the same species of Sphæria in common, but this seems to differ from all others. We have only seen it on Potentilla verna., lying upon the surface of the leaf.
Fig. 3. S. Tofieldiæ.
THIS differs from the last in being immersed in the leaf of Tofieldia palulstris.
Fig. 4. S. pustulata.
IN the cuticle of some trees this forms a flattish pustule.
Fig. 5. S. Corni.
THIS Sphæria is found on Cornus suecica. It lies under the cuticle, but stains it black, so as to make it appear as the upper surface of itself.
