of Scotland, in lat. 57° north. It is less rare in Britain than has been supposed, and appears to be more common 

 in temperate than in tropical regions.

 lobis laciniatis elongatis mbcarniculaiis retuso-truncatis, supra lacunoso pallido flavescente (s. rufeseente),

 riere Island (on wood), Sinclair. 



Allied to the preceding, but having exactly the habit of the S.foveolata, Del., from which it can scarcely be 

 distinguished when the cyphelte are obsolete. The broader forms are not altogether unlike S. pnlmonacea, as Delise 

 observes. In spite of a certain amount of variation in the length and breadth of the segments of the thallus, and 

 of the more or less tomentose or quite naked under side, 8. carpoloma is in general easily recognized by its deeply 

 laeunose and forked lobes : the apothecia and medullary stratum agree with 8. crocata. In the Hookerian Her- 

 barium is a fragment senfby Dr. Montagne, who has compared Delise's plant, which was collected in Chili, the 

 only other station for our Lichen, so far as we know. This plant does not bear soredia or coralline processes.—

Hab. Middle Island, D' Urville. 



Dr. Montagne descnoes the apothecia as "marginalia, subsessilia, disco fusco-badio piano, margine decorticato 

 purpurascente" (Fl. Fernand. n. 73). He inclines to unite S. aurigera, Del., to this species. I am sorry not to 

 have an authentic specimen of this Lichen ; the colour of the medullary stratum is not noticed by the authors men- 

 tioned. Mr. Colenso has collected what is probably the same plant : if so, it is white. 



§ 2. Cyphellte white or pale yellow; either punctiform, or explanate, or urceolate. (Leucosticta, Bab.) [Spe- 

 cies of this section are found in almost all parts of the world, but by far the greater part occur in the 

 temperate and frigid regions of the south. No Lichens present greater difficulties as to the limitation 

 of species than this group.] 

 A. Stipitat*, Bab.— Thallus contracted at the base into a thick, distinct, woody stem ; frond flabellate, more or 



less distinctly costale. Apothecia not hairy. 

 8. Sticta filicina, Aeh., Meth. Lie A. p. Zl&.—IIoffm. PI. Lick. t. 55 {opt.). 

 Hab. Northern and Middle Islands, on rotten wood, Forster, Menzies, etc. 



Hoffmann's figure is so excellent, that little need be said of this species ; the elongated stipes, the decompound 

 and dissected, and very strongly costate, thallus, the elegantly coloured, ferruginous, minutely tomentose underside, 

 and minute urceolated cyphelke, distinguish it readily from every Lichen with which I am acquainted. Dr. Mon- 

 tagne in his valuable account of the Lichens of the Canary Islands (p. 106 in Webb and Berthelot's Hist. Can.), 

 thinks S. Sufourii the same as S. filicina. I am indebted to his kindness for a French specimen of the former plant, 

 which seems to me altogether a different Lichen, though belonging to the present Section ; its ally is rather S.fuh- 

 ginom, with which it accords in most respects, except in the more or less distinct, elongated, woody stipes, and 

 costate thallus. Dr. Hooker's 8. filicina ! from Cape Horn (Fl. Antarct. p. 523), clearly appears to belong to 8,
