Readily distinguished by the mode of growth and the form of the 

 elegantly divided granules. The podetia are very closely adnate to the 

 substratum, and the apothecia are numerous. The cephalodia are grevish, 

 sometimes caesio-greyish, opaque, verrucose, minutely granulate ou the 

 surface, with the gouimia in gelatinous nodules. The spermogones ai-e at 

 fii-st simple, afterwards compound, with the spermiitia 0,005-0 mm. long, 

 0,001 mm. thick.

2. S. Delisei Bory in Dub. Bot. Gall. ii. (1830) p. 619.— Thallus 

 small, podetia loosely ceespitose, branched, the axis thinly arachnoid 

 or often naked : podetial granules situated chiefly towards the 

 apices, crenate or digitately divided, whitish, pulveruleuto- dissolved, 

 eorediato-conglomerate ou the apices. Apothecia unknown. —

The granules at first resemble those of S. coralloides, but at length 

 become pulverulent and sorediite at the apices. Our British specimens, 

 which are without cephalodia, have the podetia scarcely i in. high, with
