Fig. 4. S. parallela.
THE surface of this is often nearly smooth. The sphærules are more or less in number, imbedded in a blackish substance which rises above the burst cuticle, Handing in little parallel patches above it.
Fig. 5. S. Picea.
THIS is irregular, and smooth on the surface, resembling dry pitch, partly bleached to a brownish colour, and cracked. The sphærules are imbedded, but the whole Fungus lies on the outside of the wood on which it grows.
Fig. 6. S. convergens. Tode Fung. Meckl. t. 14 fig. 111.
THIS species rises from the cortex in a peculiar manner, similar to a parcel of flasks, having 4, 5, 6, or more together, pressing the cuticle in a convergent manner upwards, and perforating it: their mouths are just seen through it. This species can scarcely be understood without cutting it in a transverse direction.
Fig. 7. S. oblonga.
THIS species is somewhat allied to the preceding, but the cuticle is perforated in an oblong manner and nearly transverse direction. The bases of the sphærules are irregularly seated; their necks are converged, more or less curved, and longer than the last.
Fig. 8. S. tuberculosa. With. &c.
THIS seems sometimes to form sphærules round its surface, at other times not. When without those sphærules it often exactly agrees with the external appearance of L. pisiforme, tab. 271. E. Fungi; and sometimes resembles as small S. fraxinea, tab. 160. E. Fungi; and we suspected L. acariforme might also belong to it. Some specimens the Rev. Mr. Francis lately sent me confirm this, and he agrees with me. He also thinks that my figure of L. radiatum is nearly allied to it; other friends have formed the same conjecture.
Fig. 9. S. irregularis.
THIS Sphæria is irregular two different ways. It forms irregular tubercles of a brownish black; the substance being of a reddish brown, including sphærules scattered irregularly in it.
