CLADONIA. | CLADONIEI. 127 
A. PH ZOCARPA.—Apothecia brown or pale. 
a. Macrophylline.—Thallus foliaceo-laciniose ; podetia usually 
little developed. 
1. C. endiviefolia Fr. Lich. Eur. (1831) p. 212.—Thallus large 
and rigid at the base; lacinis multifid, long, flexuose, generally 
crenulate at the rounded apices, yellowish or glaucous-green, beneath 
pale straw-coloured or whitish ; podetia small, cylindrical, simple, 
rarely irregularly scyphiferous, arising from the upper surface of 
the lacinie (Kt+yellowish, K(CaCl)+deeper yellow). Apothecia 
more or less confluent, pale or brown; spores oblong, 0,011-13 mm. 
long, 0,0035-0,004 mm. thick.—Mnudd, Man. p. 52; Brit. Clad. 
p- 2; Cromb. Lich. Brit. p. 18; Leight. Lich. Fl. p. 55, ed. 3, p. 53.

The basal thallus is larger than in the other species, the lacinis being 
often 1-2 inches long and } inch broad. The yellowish-green colour of 
the upper and the paler yellow of the under surface, turned up in dry 
weather, render this a beautiful plant. It varies in size, and the smaller 
and more divided states are with difficulty distinguished from other 
species. The apothecia are extremely rare and little developed in this 
country. . 
Hab. On dry sandy (usually calcareous) soil among mosses and short 
grasses, chiefly in maritime districts.—Distr. Local and scarce, in a few 
lozalities in E. and 8. England.—B. M.: Hemsby, near Yarmouth, Suf- 
folk; Banstead Downs, Surrey ; Newhaven, Sussex (fruit). 
2. C. alcicornis Floerke, Clad. (1828) p. 23.—Thallus somewhat 
large and rigid at the base; lacinize multifid, often almost palmately 
divided, more or less blackish-fibrillose at the margins, glaucous- 
green or yellowish, beneath whitish straw-coloured or nearly white ; 
podetia arising from the upper surface of the lacinise, small or 
moderate, usually narrowly scyphiferous, scyphi cristate at the 
margins (K—, K(CaCl)+deep yellow). Apothecia often confluent, 
brown; spores as in the preceding species.—Cromb. Lich. Brit.

In its typical condition this may be distinguished from the preceding 
by the more divided, narrower, and congested thallus, which is sometimes 
pale rose-coloured beneath, and by the blackish fibrillose margins of the
