Usually spreads very extensively, though often suhdeterminate. I t
varies somevliat iu thickness, being either moderate and granii ose, or
thinnish aud almost leprose, and also in colour from gTeenisli-white to
dark-o-reyish, according to substratum and expopre. lliese mmoi and
accidental differences gave rise to the enumeration of supposed species,
none of which, however, can rank even as forms. I h e apothecia aie
usually very numerous, simple, or conglomerate, with the stipes occasionally
branched, and when dry sulcato-corrugate.

Distino-uished by the more squamulose thallus and smaller apothecia.
I t is subsimilar to B. carneus Flork., which does not occur m our Islands,
and which, though generally regarded as a var. of B. riifus, is a distinct
species. In B. carneus the thallus is squamulose, with the squamules
eontio'uous, inciso-crenate, the podetia distinctly, though-shortly stipitate,
and the thalline reaction K-|-yellow, and then immediately s_afiron-red
(ride Nyl. Flora, 1877, p. 462). In this variety the thallus is usually
orbicular and moderate in size, with the apothecia minute and scattered,
though two or three often become conglomerate, and in a dry state
entirely sessile.
Hab. On sandy and peaty soil, rarely on putrid wood, in exposed mantime
and upland situations.—DIsir. Local and scarce in the Channel
Islands, S. and S.AV. England; more plentiful among the Grampians.—

In general aspect the sterile plant resembles Bhxjscia jiitrjrea, but the
thallus is opaque and more entire, glaucous when moist, and the habitat
is entirely different. The apothecia, which are very rare and seldom fully
developed in Great Britain, are central, several being aggregate and
almost confluent on the divided apex of the stipes.
Hab. On gravelly soil among heaths in upland moorland districts.—
Histr. Local and scarce in the mountainous tracts of N. AVales, N. England,
and S. and N. Scotland, more frequent among the Grampians.—
