This differs chiefly in the form of the apices of the podetia, and appa- 
rently never occurs with apothecia. 
Hab. On putrid trunks and turf-walls in shady upland districts. —Distr. 
Apparently local and scarce in S.W. and N. England and among the 
Central Scottish Grampians.—B. M.: Beckey Falls, 8, Devon; near Bod- 
min, Cornwall; Loundsdale, Cleveland, Yorkshire; Ennerdale, Cumber- 
land. Rannoch, Perthshire ; Loch Linnhe, Inverness-shire. 
14. C. verticillata Florke, Clad. (1828) p. 26.—Thallus foliaceo- 
squamulose at the base; leaflets few, small, laciniiform, crenato- 
incised, dark-olive or greyish-green; podetia corticate, glabrous, 
elongato-turbinate, scyphiferous, glaucous- or brownish-green ; 
scyphi regular, plane, denticulate at the margin, at length repeatedly 
proliferous (2-4 times) from the somewhat elevated centre (K—, 
CaCl—). Apothecia moderate, brown or reddish.—Leight. Lich. Fl.

From C. gracilis, of which some make it a variety or subspecies, this is 
distinguished by the scyphi being at length 2-4 times proliferous from 
the centre, the uppermost scyphus being shorter and narrower. It 
approaches also C. verticillaris Mont., but is well separated by the basal 
thallus. In this country it is rarely fertile. 
Hab. On mossy rocks and boulders in maritime and upland districts.— 
Distr, Local and scarce in §., W., and N. England, very rare in Scotland 
andin N.W. Ireland (Connemara, Galway), as also in the Channel Islands ; 
though it isno doubt more generally distributed —B, M. : Noirmont, Island 
of Jersey. Broadwater Forest, Sussex; St. Breock, Cornwall; Delamere 
Forest, Cheshire; Ayton Moor and Baysdale, Cleveland, Yorkshire ;

Form laciniolata Nyl. ex Cromb. Grevillea, xi. (1883) p. 112.— 
Lacinie elongate and narrow at the base; podetia with the scyphi 
laciniolose at the margins. 
This may be a distinct variety. It is a luxuriant plant, with the apo- 
thecia numerous and dark brown. 
Hab, On exposed rocks in moist places in upland districts— Distr. 
Found only sparingly in S.W. England and the 8.W. Highlands, Scot- 
land.—B. M.: Carn Galva, near Penzance, Cornwall. Barcaldine, 
Argyleshire.
