436 CYCLOCARPINEX [CLADONIA 
times large but usually small, greenish-grey above, white beneath ; 
podetia slender, elongate, rather cylindrical, simple or branched, 
ascyphous, irregularly branched, acuminate at the apices, decorti- 
cate and granular-furfuraceous ; greyish-white (K + yellowish, © 
CaCl —). Apothecia terminal, small, brown ; spores fusiform or 
ovoid, 10-16 p» long, 3-4 » thick.—Cromb. in Greyvillea xi. p. 112

Near to C. pityrea, but distinct in the constantly pointed branches. 
Hab. On the ground among mosses in subalpine districts.— Distr. 
Local and scarce among the Grampians, Scotland, and in N.W. Ireland 
(Galway).—B. M. Head of Glen Callater, Braemar, Aberdeenshire. 
3. Podetia partly or entirely corticate, often ascyphous. 
Basal squamules rather large.

Primary thallus rather scanty, the squamules small, crenate at 
the margins, glaucous-green above, white beneath; podetia 
moderate in size, smooth at first then warted, uneven, and tomen- 
tose between the scattered corticate areole, rarely squamulose, 
whitish or pale-greenish, becoming black, especially at the base 
and then punctate (maculate) with the light-coloured areole 
scyphiferous, the scyphi often radiate or proliferous at the 
margins (K —, CaCl —). Apothecia rather large, brown ; para- 
physes clavate at the tips; spores 10-11] p long, 3°5 p thick.—

The distinguishing though sometimes obscure character of this 
and the following species is the blackening of the subcortial layer of 
the podetium, especially at the base, while the scattered particles 
of the cortex remain unchanged. Inf. granulifera the cortical areole 
are swollen and partly squamulose, giving the podetium a coarsely 
granular appearance. Forms haplotea and euphorea represent states 
when the scyphi are more or less proliferous or cristate at the margins. 
Hab. On the ground in alpine and subalpine regions.—Distr. 
Rather rare among the Scottish Grampians.—B. M. Pass of Leny, 
Perthshire ; Ben-naboord, Upper Glen Dee and Cairngorm, Braemar, 
Aberdeenshire.
