142 LICHENACEL. [CLADONIA, 
Cladonia gracilis var. cornuta Leight. Lich. Fl. p. 62, ed. 3, p. 58. 
Lichen cornutus Linn. Sp. Pl. (1758) p. 1152.—This is not Lichen 
cornutus of British authors: vide C. jibula var. subcornuta and 
C. macilenta. 
Though by some regarded as a variety or subspecies of C. gracilis, yet 
from the podetia being corticate only to beyond the middle and then more 
or less pulverulent upwards, it may rank as a distinct species. The basal 
leaflets are not unfrequently present ; and the podetia, which are 2-4 in, 
high, are quite naked. In British specimens the apothecia and spermo- 
gones are extremely rare. 
Hab, Among mosses on the ground on heaths and in woods in upland 
tracts.—Distr. Seen only from N. England and the Grampians, Scotland. 
—B. M.: Ayton Moor, Cleveland, Yorkshire. Sherriffmuir, near Stir- 
ling; Rannoch and Killiecrankie, Perthshire ; Ballochbuie Forest, Braemar, 
Aberdeenshire ; Rothiemurchus, Inverness-shire. 
Form clavulus Fr. Lich. Eur. (1831) p. 225.—Podetia short, 
somewhat turgid, corticate from below the middle; scyphi none. 
A stunted, stouter form, with the podetia sometimes pulverulent 
throughout, except towards the base. It apparently never occurs scyphi- 
ferous or fertile. 
Hab. On turf-walls in upland districts —Distr. Extremely local and 
scarce among the Central and N. Grampians, Scotland.—B, M.: Rannoch, 
Perthshire; Glen Quoich, Braemar. 
13. C. ochrochlora Flérke, Clad. (1821) p. 75.—Thallus foliaceo- 
squamulose at the base ; squamules laciniato-crenate, greenish above, 
white beneath; podetia somewhat short, cylindrical, glabrous in the 
lower portion and pale greenish-grey, pulverulent above and whitish 
or ochroleucous, obtuse and truncate at the apices or narrowly 
scyphiferous, with the margins dentato-radiate (K—, CaCl—). 
Apothecia small, pale brown.—Cromb. Grevillea, xi. p. 112.— Cla- 
donia gracilis var. ochrochlora Leight. Lich. Fl. p. 63, ed. 3, p. 59. 
C. pyxidata &. ochrochlora Mudd, Brit. Clad. p. 14.—Brit. Exs.: 
Mudd, Clad. 24-26. 
This approaches in some respects subsp. C. fibula, and in others 
C. cornuta ; but as it constantly preserves its own type, it may be regarded 
as distinct. The podetia are occasionally sparingly squamulose (var. phyl- 
lostrota Flérke), and the scyphi are rarely proliferous. In this country 
it seldom occurs fertile, though the spermogones are not uncommon. 
Hab. On putrid trunks and turfy soil in wooded upland districts — 
Distr. Somewhat local and rare in 8.W. and N. England, in S. Scotland, 
and in the W. Highlands—B. M.: Near Beckey Falls, 8. Devon; near 
Bodmin, Cornwall; Malvern, Worcestershire ; Dolgelly, Merionethshire ; 
Cleveland, Yorkshire; Windermere, Westmoreland. New Galloway, 
Kirkeudbrightshire ; Barcaldine, Argyleshire ; Loch Katrine, Perthshire ; 
8. of Fort William, Inverness-shire. 
Form ceratodes Flérke, Clad. (1821) p. 77.—Podetia slender, 
cylindrical or somewhat ventricose, simple, subulate at the apices. —
