290 CONTllIBUTIONS TO BRITISH LICHENOLOGY, 
me to be L.fuUginosa (fov two plants occur on tlie same stoue) is a 
well-marked species allied to X. lurida or i. glohifera^ but much 
smaller iu all its parts, 
X. mnguineo-atra^ Acli. — Ben Lawers (Jones). 
L.fmco-ruhens^ Nyl. Licli, Scaud, p, 199, — Scotland and Glcnann, 
north of Ireland (Jones). On bark near Lewes, Sussex (Larbalestier, 
fide Nyl.). 
L. glcbidom, Pr. — Jersey (Larbalestier). This fine species is quite 
different from Lichen glebulosus^ Sm., which belongs to Lecidta 
coardata, 
X. vernalisy Ach. ; Nyl. Lich. Scand. p. 200. — On mosses, Ben 
Lawers (Jones), This is the true plant identical with arctic specimens 
sent by Pries, and also with others collected by myself at Kaafjord, 
Norway. 
X. oclirococca, Nyl. Lich. Scand. p, 206. — On aged F'mrts sylvestris^ 
at Inverouran (Jones) and Glenfalloch, Scotland (Carroll). This 
species is incorrectly given as Irish in Mudd's Man. p. 194. 
X. violacea, Crouan, Nyl, in Flora, 1862, p. 464. — Lerwick, Zet- 
land (Jones). Apothecia minute, scarcely visible until the plant is 
moistened, when they are seen almost hyaline and of a pale-bluish or 
violet tint. Spores oblong, 3-septate, 8 in asci. This is nearly allied to 
Lecayiora atJiroocarjia^ Dub., but differs in its biatorine apothecia and 
indistinct paraphyses. 
L. mammillarisy Gouan; Thalloidirna mammillai'e, Mudd, Man. p. 
173. — Babbicomb, Devonshire (Jones).

Fr, Lich, Arct. p. 205. — Very rare. On moss, summit of Ben Lawers 
(Jones). I did not find this fine arctic species last summer, although 
shown the exact spot where Admiral Jones had gathered it. His spe- 
cimens are identical with those from Fries.
