Mr. Hardy on Lichens of the Eastern Borders. 427 



radiately divided at the circumference, gathered up into a ridge all round be- 

 fore the extreme edge, so that the margin is plaited like a frill, smoother and 

 lighter grey towards the edge, hut the edge itself is always russet brown. 

 Younger states are flatter and not so rugose in the middle. The surface is more 

 shining than in c'lrcinata, and is rougher, being covered all over with minute 

 granules ; and this has not the glaucous tint of that lichen ; but it may be the

 (fnsco-punctato) aniUtu radioso-lohafo, apotJiecii.i fuscornfis, margine tliallode 

 Jlexuoso. Ad saxa duriora Alpium Helvetice." 



12. Lecania polioph^a, Wahlb. |3. spodoph^a, Wahlh. N. On re- 

 examination of my specimens I find a small piece of this from rocks on the sea- 

 shore to the north of Bamborough Castle. 



13. Rinodina exigua, AcJi. The plant as it grows at Bamborough belongs 

 to var. (3. metabolica, Ach. 



7. HORIZA, Fw. Small fragments on the bark of a sallow near Penmanshiel. 



14. Lecanora albella, Pers. 3. angulosa, Ach. On the bark of sallow 

 and alder, near Penmanshiel, and on alder in the Pease dean. 



y. Hageni, Ach. On old pales near Penmanshiel. 



15. Lecanora Orosthea, Ach. " Thallns tartareo-farinosus incequabilis 

 tenuissime rimulosus sulphureus I. pallide ochraceus, Q deliquescettte ochroleucus^'), 

 protothallo alio Jtbrilloso. Apothecia prima innata disco Inteolo-pallido mox pro.

On the shady face of steep rocks in dark deans. B. On slate at the Black 

 Craig, Pease dean, producing fruit ; also in Harelawside dean in a deliquescent 

 state, with the fruit scarce and imperfect. The Rev. T. Salwey sent me a speci- 

 men agreeing with ours from " the perpendicular north face of a schistose rock 

 near Barmouth," Merionethshire. This has hitherto been confounded with the 

 var. Orosthea of Lecanora varia, but has no connection with that species what- 

 ever. It is nearly allied to L. sulphurea. 



16. Biatorella Resins, Fries. I cite this species to record a plant closely 

 resembling it, but whether Lichen or Fungus, it is not easy to determine. It 

 grows without any thallus as a parasite on the resin of larches in Penmanshiel 

 Wood; very much resembles B. Resince, but is always a little larger, innate in 

 the resin, the disc slightly concave when dry, plane M'hen moistened, without 

 the paler margin of B. Resince, yellowish-brown. I sent it to Dr. Lindsay in 

 1856, and his reply was, " seems to be a new British species. The nearest 

 genus is Sarcogyne, Koerber, p. 266 ; the spores being innumerable and very 

 minute." 



17. Lecidea atro-sanguinea. Having obtained better specimens of Bia- 

 torclla pruinosa, 3. regularis, I see that the slate lichen which I took for L. atro- 

 sanguinea should rather rank with it. These are so similar that Schaerer ranks 

 them both as varieties of one species, his Lecidea immersa. 



18. Cyphelium CHRYSOCEPHALUM, Turn. I have found this fine species
