S P E C IF IC CHARACTER.
Sphæria lig n a ria ; sphoeridis minutis, solitariis vel subcongestis, nigris, ovatis,
setoso-rugosis, astomis; sporulis ovalibus in tubis cylindricis.
Sph. spherules minute, solitary or somewhat clustered, black, ovate, setoso-

H ab. On wood. Appin, Captain Carmichael.
Spherules very minute, a cluster of four or five not being larger than a Pop-
py-seed ; deep black, ovate, rough with a very short and coarse villosity.
They often originate from beneath the surface of the wood on
which they grow, but penetrate through it, and at length become sessile.
I can find no trace of an orifice. Sporules oval, yellowish, contained
in filiform, hyaline, cylindrical tubes
To Captain C a r m i c h a e l , author of the excellent account
of Tristan d’Acunha, in the twelfth volume of Linnean
Transactions, 1 am indebted for this, and a great number of
otber new Cryptogamie plants, which will from time to time
find a place in this publication. Few botanists have been more
successful than that gentleman, especially in the discovery of
rare marine vegetables.
