t. 468. f. 2. fid. Purt. E.) On the authority of Dr. Sibthorpe, who 
observed it on the fallen branches of trees. (Nearly resembling Sph. 
depress a. E.) 
(Sph. pulvina'ta. Black, elevated, rough; capsules of two different 
sizes, incorporated, their tubes projecting. 
Hoffm. 1. 2. 3. 
Grows in small convex rough patches fixed to the wood, and forcing their 
way through the outer bark, which closely embraces them at the base. 
These patches are brown, black, and very rough, being formed by the pro¬ 
jecting tubes of the capsules. The capsules are of two kinds, the one 
larger, filled with black powder, the other containing a whitish spongy 
substance. They are both invested by a common covering, which is black 
on the outside, white within when young, but nearly black when old. 
(Spherules erect, large, piercing the surface; broad at their base, gra¬ 
dually narrowing to a conical point. Purt. 
Rough-cushioned Sphxeria. This species of Hoffman was first dis¬ 
covered in Britain by Mr Brown, growing on dry, but not much decayed, 
branches, in Roslin wood, near Edinburgh. Jan. E.) 
Sph. BRAs'siCiE. Of various shapes, black; flesh white. Dicks. 23. 
(Hojfm. Crypt, ii. 5. 2. E.)— Bolt. 119. 2. 
Crust none. Spherules simple, often confluent, of various shapes and sizes, 
from that of mustard seed to that of a pea. Dicks. 
(Cabbage Sphjeria. E.) Elvela Lmassicce. Hoffman. Certainly not pro¬ 
perly a Sphaeria. 
On decayed leaves of cabbage, vulgarly supposed to be cabbage seed, and 
on decayed roots of parsnips ; common. 
TRIC'HIA.* In clusters: mostly fixed to a membranaceous 
base; capsules globular or oblong; seeds 
escaping from its whole surface through 
openings made by the separation of the fibres. 
Obs. Capsules globular, oblong, turban-shaped, or nearly cylindrical, trans¬ 
parent, in colour and tenacity like cream. Opake when older, columnar, 
filled with woolly fibres, its coat composed of a fibrous texture, at first 
compact, opening gradually, and then resembling a lock of wool, the 
seeds escaping through every part of the surface. This includes also the 
Sphserocarpus of Buliiard, which seems to differ only in consistence. 
(1) With a stem. 
Tric. nu'da. Rusty brown: stem hair-like; capsule egg-oblong, 
changing to cylindrical, perforated by the stem.
