3. B. leitcomela, Ach. (black-haired Borrerd); thallus spreading
smooth white on both sides channelled and powdery beneath, the
segments linear fringed with long black very slender hairs,
apothecia stalked bluish-black with a white radiating border.

Upon the ground among Thyme, &c, near the sea at Babbicombe and
Torbav, Hooker.— This varies somewhat from the exotic state of 13.
leucomela, in having broader segments to the thallus, of a less pure white,
and with more branching cilia : yet both in its appearance and place of
growth, it is very different from B. ciliaris, to which, if I mistake not, Mr.
Eorrer is disposed and perhaps, correctly, to refer it. The fruit has not
been detected, but is described above by Sir J. E. Smith from St, Helena
specimens.
4. B. furfuracea, Ach. (branny Borrerci); thallus spreading
ascending greyish-green farinaceous the segments linear attenuated
much divided and forked, the margin recurved, deeply
grooved rugged and almost black beneath, apothecia scattered
very concave inflated red-brown with a thin inflexed border.

Trunks and branches of old trees, especially when they are verging
to decay, and on old pales.—This is a large and remarkably handsome
species: nor are its apothecia of very unfrequent occurrence.
5. B. Atldntica, Ach. (Atlantic Borrerd); thallus erect greybrown
downy much and Intricately branched, the segments
linear deeply grooved the margins revolutej apothecia scattered,
the disk nearly flat blackish-brown with a thick entire border.

On Elms, at Bracklesham in Lelsey island ; and on the cliffs near
Hastings, abundant. Mr. Borrer.—This highly interesting plant is, like />'.
leitcomela, B. chrysophthalma and B.Jlavicatu, confined to the southern
and wanner parts of the kingdom, where they seem to have attained their
northern limits.
