Lichen pezizoides Weber, Spicil. (1778) p. 200, seems doubtfully 
referable to this species, but denotes rather the following.—Brit.

Easily recognized from its British allies by the thallus and apothecia. 
The thallus is occasionally somewhat extended, and varies in colour ac- 
cording to the substratum and exposure, The apothecia are numerous 
and crowded, becoming somewhat flexuose, and vary in colour like the 
thallus. When growing on mosses in shady situations, it is ceesio-greyish 
with the squamules less imbricate and with paler apothecia; it is then

again it is much darker in colour (as are also the apothecia) with the 
hypothallus blackish. 
Hab, On the ground and among rocks on decayed mosses, seldom on 
semiputrid stumps, in upland, rarely in alpine situations.— Distr. General 
and not uncommon in maritime and mountainous districts of Great Britain 
and Ireland.—B. M.: Dolgelly, Barmouth, and Cwm Bychan, Merioneth-

Apothecia small, plane or somewhat cunvex, crowned with the 
granulose thallus, red or reddish-brown, internally pale-whitish ; 
spores ellipsoid or fusiformi-oblong, 0,015-24 mm. long, 0,006-9

iodine.—Cromb. Lich. Brit. p. 42; Leight. Lich. FI. p. 168, ed. 3,

Distinguished from the preceding by the colour of the granulose crus- 
taceous thallus and by the smaller spores. The thallus sometimes spreads 
extensively, is but loosely coherent and very friable. The apothecia, 
which are usually numerous, are superficial or innate, becoming at length
