 are ajjproximate and radiating. The apothecia are chiefly central, nume- 

 rous and crowded, becoming larger and deformed in age, with the margin 

 at length flexuose.

Looks almost a distinct species, but is connected with the type by in- 

 termediate states. It is, however, in its most characteristic form, well 

 distinguished by the densely granuloso-pulverulent (in old plants sore- 

 diate) thallus, with the laciniae often visible only at the immediate cir- 

 cumference. With us it is rarely fertile, and, even when present, the 

 apothecia are few and scattered.
