This subspecies is somewhat variable in size, and in some of its smaller 
states is closely appressed to the substratum. The broader laciniee, which 
are occasionally convex, are often covered with spermogoniiferous ver- 
rucee and young apothecia; the former have been mistaken by British 
authors for the granulose soredia of R. polymorpha. It is usually in- 
fertile. 
Hab. On rocks in maritime tracts and on mountains.—-Distr. Not gen- 
eral nor common in the Channel Islands, 8., W., and N. England, on the 
N.E. coast of Scotland, and probably also among the Grampians.—B. M.: 
Coast of Guernsey and Island of Sark. Lustleigh Cleeve, Dartmoor, 
Devonshire; Tintagel and Polperro, Cornwall; Gower Peninsula, Gla- 
morganshire; Moel-y-golfa, Montgomeryshire; near Thirsk and on top 
of Roseberry, Yorkshire. Portlethen, Kincardineshire. 
Form gracilescens Cromb. Grevillea, vii. (1879) p. 141.—Thallus 
very small, pulvinato-congested, lacinie short, slender, shortly 
divided at the apices, which are finely incurved or revolute. Apo- 
thecia not seen. 
The characters given separate this form, which otherwise-agrees with 
thé type. No apothecia have been seen, but spermogones are sparingly 
present. 
Hab. On boulders and walls in maritime tracts.— Distr, Local and rare 
in the Channel Islands and 8. England, but may occur elsewhere.— 
B. M..; Island of Sark. Near Brighton, Sussex. 
12. R. Curnowii Cromb. ex Nyl. Flora, 1875, p. 441.—Thallus 
fruticulose, subrigid, slender, rounded or somewhat compressed, 
shining, sparingly branched and but slightly interwoven, pale glau- 
cous (medulla K—). Apothecia terminal and lateral, small or nearly 
moderate, convex, pale, geniculato-adnate, the receptacle smooth ; 
spores ellipsoid, straight, 0,011-15 mm. long, 0,004-6 mm. thick.

Allied to RB. cuspidata, though, as stated by Nylander 2. c., the colour 
of the spermogones might lead us to place it in the section of R. carpa- 
thica. The thallus, which is moderate or more or less elongate (from 2 to 
6 inches in length), is blackish towards the base, and the laciniz, for the 
most part simplish (rarely branched towards the apices), are usually 
narrow, though varying somewhat in breadth. When fertile the apo- 
thecia are numerous. ‘The blackish spermogones are frequent, with sper- 
matia 0,003 mm. long, 0,001 mm. thick,
