of Its external appearance, and by the spondia being very much longer

Forming short parallel lines ; perithecia minute, subglobose,
raising and at length cracking the cuticle, black, in short lines ;
ostiola acute, sometimes piercing the cuticle ; sporidia biseriate,
or clustered, elliptic, uniseptate, slightly constricted, the upper
cell somewhat swollen, hyaline.
On stems of Pteris aquilina. May. Shere. (Dr. C.)
Easily confounded with small forms of Dothidea filicina, but the lines are
less distinct, and, on remo-ving the cuticle the perithecia are decided. Quite
distinct from S.pantherina, to which it is allied.

or more obscure septa.—Berk. exs. no.'34. Mag. Zool. & Bot.no.

On Pteris aquilina.
At first sight resembling S. pardalota. I t differs, however, in the immersed
perithecia and the elongated neck. The line is not always visible externally,
but it may always be found on making a transverse section, being in fact the
edge of a true conceptaculum. When the line is visible externally the cuticle
is nearly unaltered, when, on the contrary, it is obscure the cuticle has a
brown burnt appearauce.—ilf.
The stylospores of this species are fusiform and extremely narrow, ÜUU8-
'001 in. long (see C^lrr. Linn. Tran$. xxii.p. 285).
