Stizenberger considered this plant to be intermediate between 

 B. effusa 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
