3. B. leitcomela, Ach. (black-haired Borrerd); thallus spreading

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 attenu- 

 ated 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 grey- 

 brown 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.
