Distinguished from B. rufus by the longer podetia and by the 
colour of the apothecia. The thallus spreads extensively, and is often 
sprinkled with globose white or rosy-white granules. The apothecia 
are somewhat rare, but the rather large spermogones, which are 
blackish above, are frequent; the spermatia are 5» long and ly 
thick. Lichen ericetorum L. Sp. Pl. p. 1141 (1753) is B. wruginosus 
(Iemadophila ericetorum, p. 352).
