Form subfurcata Nyl. ex Norrl. Not, Sallsk. pro F . ot Fl. Fenn.
Fòlli. 11. s. X. (1873) p. 320.— l ’odotia elongate, subulate, substipate,
fastigiate, branched upwards, gramilato-iinequal on tho
surface, brownish. Apotheoia not seen.-—Cromb. Grevillea, xi.
p. 113.
Tliis very peculiar form is as if an hybrid between C. degenerans and
C. furcata, to Avlncli latter, bnt for the granulate podetia, it miglit be
referred as a variety. The absence of any reaction with K keeps it
distinct from Cladonia sti-ictu. Iu this country, as elscAvhere, it is alwaj'S
sterile.
ITab. On moist peaty ground in subalpine tracts.—Distr. Found only
very sparingly among the N. Scottish Grampians.—B. AI. : Upper Glen
Uee, Braemar, Aberdeenshire.
Subsp. 2. C. coralloidea Nyl. Lich. Scand. (1861) p. 54.—Thallus
small, somewhat pulvinate ; podetia short, branched above, sub-
flexuose, verrucoso or gran u la te on the surface, ascyphous. Apothecia
small, croAvded, brown.— Cromb. Grevillea, xv. p. 45 .— Cladonia

Though receding in various respects from the type, this, according to
the specimen from Acharius in Herb. Linn. Soc., is most probably to be
regarded as a siib.species of C. degenercms. I t is not unlike C furcata
var. palameca (Acb.), but at once differs from this by having a distinct
basal tballus. Tbe only Britisli specimens seen agree Avitli the plant of
Acliarius, except th a t the podetia are partly subsquamulose. The apothecia
seem to be not uiifrequent.
Ilah. On tlie ground on wet heaths in mountainous districts.—Distr.
Very local aud scarce in N. England and aniong the S. Grampians, Scotland.—

19. C. lepidota Nyl. Not. Sallsk. pro F. e t Fl. Fenn. Forh. n. s.
V. (1866) p. 176.— Thallus squamulose a t th e b ase: squamules
somewhat large, crenato-incised, pale glaucous above, white beneath ;
podetia robust, pale, foliolose or squamuloso-folioloso ; soj'phi
usually narrow, irregular, difform or cristato-diyided (K-|-yellow,
CaCl — ). Apotheoia smaU, brown, conglomerate.— Cenomyce (jono-
reeja f. lepidota Ach. Syn. (1814) p. 259.
From C. degeneraiis, of which it has usually been regarded as a A'ariety,
this differs iu being more robust and paler, in having the podetia squamulose
Avitli the squamules larger (as also at the base), and in tbe
reaction with K. Tbe type, however, does not occur in our Islands, but
only the following form.
Form hypopbylla Cromb. Grevillea, xi. (1883) p. 113.— Thallus
foliaceo-squamulose, subcffispitose, groyish-whitc or greenish-grey,
Avhite b e n e a th ; podetia obsolete (K-|-yellow, CaCl —). Ajiothecia
small, sessile, dark-brown. — Cladonia degenerans f. hypophylla

A rather anomalous plant, which, if it does not descend from C. cervi-
cornis, with which it somewhat agrees in the character of the basal
squamules, is most probably referable to this species. The apothecia,
which iu the absence of rightly developed podetia are sessile on the leaflets,
are numerous.
Ilcd). On the ground among rooks in upland districts.—Distr. Some-
Avhat local, though not uncommon where it occurs in N. Wales, N. England,
S. Scotland, and among the Grampians.—B. AI.: Plinlinmion, Carnear
Stirling; Oraig Calliach and Loch Eagh, Perthshire; Lion’s Face
and Glen Qiioich, Braemar, Aberdeenshire.
V. Ascyjyliex.— Podetia not scyphiferous.
20. C. turgida Hoffm. Deutsoh. F l. ii. (1795) p. 124.—Thallus
foliaceous a t th e base ; leaflets large, laoiniiform, variously divided
and crenate, sometimes few or evanescent, glaucous-green or w hitish,
white beneath ; podetia iDcvigato-corticato, turgid, elongato-turbinate
or cylindrical, subsoyphiforous or perforate a t th e apices, th e margin
dentato-radiate, glaucous or pale-green (Kf-|-yellowish, CaCl—).
Apothecia brownish-red or p a le ; spores oblong or oblongo-fusiform,
0,010--15 mm. long. 0 ,0 0 3 5 -4 0 mm. thick.—Cromb. Lioh. Brit,
p. 20 ; Leight. Licb. F l. p. 56, ed. 3, p. 5 4.— Liehen turgidus Ehrh.
Crypt. (1793) D. 297.
When rightly developed (for the podetia are occasionally absent), this
is a very distinct species, which at first sight niiglit be referred to the niacro-
pliylline section. As stated, however, by Nylander (Syn. p. 20o), its
true affinity is with C.furcata in the present section. In the only two
Britisli specimens the podetia are here and there sprinkled Avith smaller
leaflets. There are no apothecia present, but the spermogones are abundant.
Hab. On the ground among heather in subalpine regions.—Disir.
Extremely local aud scarce among the N. Grampians, Scotland.—B. AI.:

erect, attenuato-subulate and divergeiiti-furoate a t the apices (K —,
