Stizenberger considered this plant to be intermediate between
B. effttsa or B. fuscorubella and B. muscorum, agreeing with the
latter in habitat and colour of the older apothecia, but approaching
more nearly to B. effusa in the form and size of the spores. The
thallus varies from being very granular and contiguous to dispersed,
scanty, or obsolete.
Hab. Incrusting decaying mosses on granitic rocks in maritime
tracts.—Distr. Local and scarce in the Channel Islands.—B. M. Near
Eozel, Jersey ; Port Gorey and the Bperquerie, Sark.
