a. Thallus evanescent at the base; podetia branched ; cephalodia 
sessile, glomeruliform or verrucose.

iv. p. 24.—Thallus somewhat small or usually moderate; podetia 
ceespitosely united at the base, erect or ascending, branched, the 
axis glabrous ; podetial granules digitately branched or subfibrillose, 
greyish. Apothecia moderate, terminal and lateral, at length glo- 
bose and immarginate, brown or dark-reddish ; spores 3- (rarely

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 os pe are greyish, 
sometimes ceesio-greyish, opaque, verrucose, minutely granulate on the 
surface, with the gonimia in gelatinous nodules. The spermogones are at 
first simple, afterwards compound, with the spermatia 0,005-6 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, pulverulento-dissolved, 
sorediato-conglomerate on the apices. Apothecia unknown.—

The granules at first resemble those of S. coralloides, but at length 
become pulverulent and sorediate at the apices. Our British specimens, 
which are without cephalodia, have the podetia scarcely 3 in. high, with
