1. SCLEKOTIUM, Tode. 
1. ScLEEOTiTJM CiKNAMOMi, m. (Plate LXVII. fig. 17 ; fig. 19, magnified ; diameter mag- 
nified, 19 J.) 
Scl. peritliecio orbiculato, duro, piano, margine elevate. 
On the leaf of Cinnamomum Possmdssleri there are several flat circular umbos. They 
are 1 millim. in diameter. They are quite smooth and flat in the centre, and surrounded 
by a very sharp edge. 
They very much resemble Sclerotium pustuliferum., Heer, which is often found on 
Quercus neriifolia in Oeningen. Of the living species, Scl. pustula may be compared 
with it. Eossmasslee has figured a closely resembling, but somewhat larger fungus, in 
his ‘Beitragen zur Versteinerungskunde,’ taf. 8. fig. 27. 
2. Sph^eia, Hall. 
2. Sph.®eia socialis, m. (Plate LXV. fig. 13, c; fig. 13, cc, magnified.) 
Sph. peritheciis congregatis, minutissimis, orbiculatis, ostiolo rotundato pertusis. 
In the 17th bed at Bovey. 
There are many circular and convex little bodies close together on a leaf of Bryan- 
droides laevigata, Heer. In the centre they are furnished with a pretty large aperture. 
3. SPH.iEEiA LiGNiTTJM, m. (Plate LV. fig. 1 ; figs. 2 & 3, magnified.) 
Sph. peritheciis gregaiiis, liberis, conicis, nigris, apice nitidis, papillatis, ostiolo mi- 
nuto, orbiculato. 
I found this Spheeria on the bark of several branches, which perhaps belong to Sequoia 
Couttsioe. They were lying in the 26th bed, beside some young branches of Sequoia. 
The perithecia form little black warts, which are clustered together in great numbers ; 
the largest ^ millim. in diameter ; many of them are much smaller, and appear as black 
points. The largest of them are slightly conical, and furnished on the top with a very 
small though distinctly separated cicatricule. When this cicatricule falls away, a small 
aperture is left. In many of them a transverse slit has originated near the base, 
and the upper part of the perithecium has fallen away ; thus we have a large aperture, 
surrounded by the pretty thick coat of the perithecium. 
This belongs to the group of Sphcerice pertusoe. Fries (Systema Mycolog. ii. p. 460), 
and has a great resemblance to S'phoeria umhrina, which, however, is much larger and 
flatter.
