410 Mr. Hardy 07i Lichens of the Eastern Borders. 



2. B. Gkiffithii, Smith. Not common. At the base, and about the roots of 

 old oaks in Red Clues Cleugh, and on mountain ash, Penmanshiel Wood. N. 

 On old oaks above Coldgate Mill. 



3. B. SPHJEROIDES, Diclcs. N. On a vein of calcareous spar in Humbleton 

 dean. B. On mosses in North Cleugh, Penmanshiel Wood, among moist shady 

 rocks, and on a rock beneath the Pease-bridge. A puzzling state of this occu- 

 pies the shadiest portion of the face of the rock on the east side of Routin 

 Linn, The thallus is dark green when moist, paler when dry, leprose, cracked 

 into polygons ; apothecia mostly scattered, about the middle size, sessile, thin, 

 irregular shaped, margin flexuose, the disc flat, rarely in deformed convex 

 rough tubercles, dull livid or purplish-brown, slightly primrose, the margin 

 paler. I should have felt doubtful of this, but for finding a single globose 

 apothecia of the usual form and hue. This is a form of the old Lecidca ver- 

 nalis. 



4. B ? HALOPHILA, nov. sp. Thallus e£fuse, thin, somewhat scaly, the scales 

 narrow elongate, scattered, or loosely gathered into a minutely rimulose crust ; 

 testaceo-cinereous or greyish-white ; apothecia minute, not very numerous, 

 scattered, plano-convex, never globose, flattened when moistened, finely rugu- 

 lose, margined or immarginate, sometimes silting on a scale, black, but more or 

 less purple when moistened. Among shady greywacke rocks on the sea-coast 

 at Swallow Craig, near Siccar point. The apothecia somewhat resemble those 

 of Lecidea fusco-rulcns of Nylander, (specimens of which I have from the Rev. 

 T. Salwey,) in their external appearance, but these are smooth, better margined, 

 and of a deeper purple when wet. 



5. B. SYNOTHEA, AcJi. B. On decayed pales near Penmanshiel, not com- 

 mon. This is identical with Mr. Mudd's typical example in Herb. J. G. 

 Baker, Esq. ! 



6. B ? LITTOEALIS, nov. sp. Thallus efTuse, thin, mixed with the hypothal- 

 lus(?), tartareous, mouldering, rugulose, of a darker or lighter leaden grey; 

 apothecia few and scattered, sessile on small elevations of the crust, minute, the 

 disc concave or plane, margin thickish, black, shining ; sporidia oblong-oval, 

 bilocular. In the cavities of red-sandstone rocks beat by the sea at Greenheugh 

 point, only a few specimens obtained, and those probably in a degenerate state. 

 Of this plant Mr. Mudd, who examined a fragment says, "the internal struc- 

 ture of the apothecia is similar to those of Lecavia erysihe 7. ai^pospila, Borr. ; 

 but the external aspect of the whole plant hardly corresponds with that of 

 aijjos^ila," Till better examples are procured I place it next to £, cJtalyheiu, 

 •which it somewhat resembles externally. 



7. B. CHALTfBElA, Borr. D. With a black crust on sea-side rocks near 

 Hudshead, examined by Mr. Mudd. B. With a lead-coloured crust on tiles at 

 Penmanshiel, compared with an example from Herb. Borrer ! with which the 

 Rev. T. Salwey kindly favoured me. 



8. B. GROSSA, Pers. B. Trunks of trees, moist shady deans, not common. 

 At the base of an oak in Witchy Cleugh, and on the bark of ashes, Blackburn- 

 rigg Wood, and Red Clues Cleugh ; on a hazel, Erockholes dean ; and on an 

 ash in a shady ravine, Bowshiel dean ; and running off on mosses attached to 

 the bark. Lecidea premnea, Hook. B. F. ii. p. 176 in pt.
