A very variable plant. The form liere described is Cladonia chordalis
Florke, Clad. p. 34. The ba.sal thallus is rarely visible except in young
plants, becoming for the most part speedily obsolete. I t is a social
plant, often spreading extensively, with tbe podetia 2-4 in. long, simple
or more or less branched, and frequently blackish at the hase. The apothecia
are rare; when present they are numerous aud occasionally conglomerate.
Hab. Among mosses on tbe ground and on rocks in maritime and
upland districts.—Distr. General and common in most parts of Great
Britain and probably also Ireland ; rare in tbe Channel Islands.—B. M. :

Form 1. abortiva Schær. Spic. (1823) p. 33.—Podetia subuliform,
recurved or hooked a t th e apices, and th ere verruoose, infúscate :
substerile.—Aludd, Brit. Clad. p. 17 ; Leight. Lioh. F l. p. 63, ed. 3,
p. 5 9 ; Cromb. Grevillea, xi. p. 112.—B r it. E x s .: Mudd, Clad,
n. 36.
Probably an accidental state, resulting from the abortive apotbecia
deforming tbe podetia.
Hah. On the ground in upland situations.—Distr. Seen only from N.
England aud the Central Grampians, Scotland ; no doubt occurring elsewhere.—
B. AI. ; Highcliffe, Cleveland, Yorkshire. Rannoch, Perthshire.
Form 2. spinulifera Cromb.— Podetia slender, d a rk spadiceous,
somowhat rugulose, w ith frequent short spinules ; soyphi with th e
margins spinulose.
A peculiar and probably accidental form, analogous to var. sqnnosa
of C.furcata. The only specimen yet gathered is sterile.
Hab. On moors in upland situations.—Distr. Found only in S.W.
England.—B. AI. : Near Newton Abbot, S. Devon.
Form 3. a sp e ra Fldrke, Clad. (1828) p. 30.—Podetia more or
less clothed with foliolose squamules ; squamules crenate or crenato-
incised a t the margins.— Cromb. Grevillea, xi. p, 112.— Capitidaria

—B r it. Exs. : Leight. n. 402.
Differs in the more or less squamulose podetia, which are usually
ascyphous. The British specimens are in a stunted condition, with
podetia short (scarcely more than 1 in. high), subulate and sterile.
Hah. On tbe ground in upland situations.—Distr. Local and scarce in
Central and N. England.—B. AI. ; Charnwood Forest, Leicestershire;
Ingleby Park, Cleveland, Yorkshire ; Windermere, Westmoreland.
Var. p . h y b rid a Schær. Spic. (1823) p. 32.— Podetia more or less
elongate, robust, sparingly branched, usually scyphiferous ; soyphi
subdilated or proliferous a t tbe margins. Apotheoia moderate.—

A robust plant, with the podetia for tbe most part scyphiferous. As
noticed by Nylander (Syu. p. 196), it approaches vars. of pyxidata, of
which at first sight it looks to be a more extended form. In tbe few
British specimens the apothecia are sparingly present.
Hah. On mossy rocks and among mosses on the ground in mountainous
districts.—Dîsir. Local; the Grampians, Scotland, probably not uncommon.—

; Glen Callater, Braemar, Aberdeenshire.
Subsp. C. g ra c illim a Norrl. Hb. Lich. Fenn. ix. (1882) n .4 2 4 .—
Podetia elongate, very slender, crowded, subulate or soyphiferous,
much branched above ; branches divided, shortly subfurcate a t the
apices; scyphi very narrow, denticulate a t th e margins (K—,
CaCl — ). Apotheoia not seen.—Cromb. Grevillea, xi. p. 112.
Distinguished by the slender podetia being densely cæspitose, much
and intricately branched, especially in the upper portion, and by their
apices being somewhat furcate, resembling C.furcata. Found only in a
substerile condition.
Hab. On mossy boulders in upland fir woods.—Distr. Very local and
scarce in N. England and N.E. Scotland.—B. AI. : Tbe Cheviots, Northumberland.

foliolose a t th e base ; leaflets lobato-creiiate or none ; podetia elongate,
corticate and glabrous in th e lower portion, pulverulent towards
th e apices, subuliformi-cornute or a few sometimes narrowly soyphiferous
(K—, C a C l- ) . Apothecia small, b row n ; spores as in tho
preoodiug species.—Cromb. Lioh. Brit. p. 13 ; Grevillea, xi. p. 112.—
