glaucous-green above, whitish beneath ; podetia short, cylindrical, 
glabrous, subverrucose or somewhat foliaccous, scyphiferous, greyish- 
green or glaucous-white ; scyphi dilated, proliferous from the centre 
and from the denticulate margins (K—,CaCl—). Apothecia small, 
simple or conglomerate, brown.—Cromb. Grevillea, xi. p. 113.—

Very closely allied to C. cervicornts, from which it is at once separated 
by the reaction with K. {n other respects it is distinguished chiefly by 
the somewhat smaller (rarely nearly as large) and less ceespitose thallus, 
by the margins of the seyphi and the prolifications, which are often 2, 
rarely 3, in which respect it more resembles C. verticillata, From this 
also it seems distinct, and preserves its own type. The podetia are occa- 
sionally sparingly foliaceous, and the apothecia are usually numerous. 
Hab. On mossy boulders, rocks, and the ground in upland districts.— 
Distr. Somewhat local in S., W., and N. England, the Highlands of 
Scotland, S. Ireland, and the Channel Islands; no doubt often over- 
looked.—B. M.: Grosnez Common, Island of Jersey. Near Dawlish and

17. C. macrophylla Nyl. Flora, 1873, p. 299.—Thallus squa- 
muloso-foliaceous at the base; squamules large, glaucous above, 
whitish beneath, crenate at the margins ; podetia moderate or some- 
what elongate, cylindrical, ascyphous or often with narrow scyphi, 
rough with smaller glaucous squamules, becoming at length carious 
(K+yellowish, CaCl—). Apothecia brown, generally confluent ; 
spores 0,008-0,011 mm. long, 0,0035 mm. thick.—Cromb. Grevillea, 
xi. p. 113.—Cladonia ventricosa B. macrophylla Scher. Spice. (1833) 
p. 316. 
In old age the podetia (which are then often blackish at the base, as 
are also the basal squamules at their base) become more or less carious, 
and thus somewhat resemble those of C. cartosa. From C. decorticata 
Flérke, with which it has sometimes been confounded, and which pro- 
bably also occurs in this country, it differs in the larger squamules and the 
chemical reaction. In the only fertile British specimen the apothecia are 
aggregate and deformed. 
Hab. On earth-covered boulders and oie eae ie in wooded ae 
inous regions.— Distr. Apparently very local and scarce among the 8S.
