34 Lichen geographicus.—''Eng. Bot. t. 245.—With.'' 4. 12.

On Rocks and Stones upon Gateshead Fell, and in the Neighbourhood of Egleston, D. On Rocks at Shewing Shields; on Cheviot, &c. N.

1221. Lecidea citrinella.

Lichen flavo-virescens.—''Dicks. Crypt. fasc.'' 4. 13. pl. 8. 9.—With. 4. 12.

On Earth upon the tops of Walls near Egleston, D.—H.

1222. Lecidea silacea.

Lichen silaceus.—''Eng. Bot. t.'' 1118.

On Rocks and Stones in Teesdale Forest, D. On Cheviot, N.

Obs. This Lecidea, which is Lichen silaceus of E. Bot. appears to agree with the Figure and Description of Patellaria silacea in Hoff. Pl. Lich. but is certainly different from Acharius's L. silacea. Rust-colour is not natural to this Plant.

1223. Lecidea Œderi.

On Stones in the Neighbourhood of Egleston, D.

Obs. This is very different from Lichen Œderi of ''Eng. Bot. t.'' 1117. which is Lichen cæsius of Dicks. and Dicksoni of With. Rusty red is not the natural Colour of the Crust.—H.

See Obs. under Lecidea dendritica.

1224. Lecidea privigna.

On Sandstones upon Gateshead Fell, and near Egleston, D.

Obs. This was sent to Dr. Acharius as Lichen simplex of the Linn. Trans. and therefore that Lichen is quoted as a Synonym of it, in Methodus Lichenum: it is, however, very distinct from Lichen simplex.—H.

See Obs. under L. polytropa.

1225. Lecidea niveo-ater.

See Lecidea epipolia.

1226. Lecidea picea. Rh
