Banks, Cleveland, Yorkshire. New Galloway, Kirkcudbrightshire ; 
Appin, Argyleshire; Rannoch, Perthshire; near Ballater, Aberdeenshire ; 
Loch Linnhe, Inverness-shire. Kylemore, co. Galway. 
Form hololepis Flirke Clad. (1828) p. 83,—Podetia somewhat 
short, densely squamuloso-furfuraceous ; squamules fragile, more or 
less pulverulent ; scyphi irregularly fimbriate or divided.—Cromb. 
Grevillea, xi. p. 112.—Cladonia pyxidata p. pityrea j. hololepis 
Mudd, Brit. Clad. p. 16 (non Exs. n. 33). 
This differs in the minutely squamuloso-furfuraceous podetia somewhat 
elongate when sterile. Though distinct, it is only a form, as in the type 
a few minute squamules are occasionally present. In the only British 
specimen the apothecia are somewhat numerous. 
Hab. On the ground amongst decayed heaths in upland districts.— 
Distr, Very local and scarce in the S. Highlands, Scotland, though no 
doubt occurring elsewhere.—B. M.: Glen Lochay, Killin, Perthshire. 
7. C, acuminata Norrl. Medd. Soc. pro F. et Fl. Fenn. (1876) 
p. 12.—Thallus minutely squamulose at the base; squamules 
greenish-grey above, white beneath; podetia slender, somewhat 
elongate, cylindrico-subuliform, simple or branched, acuminate at 
the apices, granulato-furfuraceous, greyish-white (K+ yellowish, 
CaCl—). Apothecia terminal, small, brown.—-Cromb. Grevillea, xi. 
p. 112.—Cladonia pywiduta p. pityrea e. acuminata Mudd, Brit. 
Clad. p. 15 (non Exs. n. 20). Cenomyce pityrea b. acuminata Ach.

Till recently this was regarded by authors as a variety of C. pityrea. 
In addition, however, to the more elongate, subulate, apically acute 
podetia, with their terminal apothecia, it is at once separated by the 
thalline reaction with K. Of the two specimens gathered in this country, 
one is fertile. 
Hab. On the ground among mosses in subalpine districts Distr. 
Very local and scarce among the N. Grampians, Scotland, and in N.W. 
Ireland (Connemara, Galway).—B. M.: Head of Glen Callater, Brae- 
mar, Aberdeenshire. 
8. C. Lamarkii Nyl. Flora, 1875, p. 447.—Thallus squamulose 
at the base ; squamules small, crenate, greyish-green above, whitish 
beneath ; podetia moderate, granulato-furfuraceous, scyphifero-pro- 
liferous, the scyphi not pervious, digitately divided at the margins, 
furcato-radiate at the apices (Kf+yellowish, then ochraceous, 
CaCl—). Apothecia small, conglomerate, brown.—Cromb. Journ. 
Bot. 1876, p. 360; Grevillea, xi. p. 112; Leight. Lich. Fl. ed. 3, 
p. 54.—Cladonia Lamarkit Del. fide Nyl.1.c. Cladonia pyxidata 
p. pityrea c. fascicularis Mudd, Brit. Clad. p. 15. 
From the two preceding species this is distinguished by the scyphi and 
by the reaction with K. In the few British specimens the podetia are 
rather short (about 3 in. long), occasionally somewhat fasciculate, with
