Distinguished by the lacinie, which are esorediate at the sides, and by 
the situation of the apothecia. The apices of the laciniz are subfasti- 
giate, with the soredia globuloso-granulose, or partly pulverulent, whitish 
and convex. It should perhaps, as Nylander suggests (/. c.), rank as a 
distinct species, intermediate between LR. polymorpha and R, pollinaria, 
In this country it is always sterile. 
Hab, On weathered granitic boulders in mountainous regions. —Distr. 
Local and scarce in N. England and in the N. Grampians, Scotland. —

7. RB. pollinaria Ach. Lich. Univ. (1810) p. 608.—Thallus sub- 
erect, somewhat elongate, subflaccid, subcompressed, sublacunoso- 
unequal, and longitudinally rngose towards the base, lacero-laciniate, 
slightly shining, pale straw-coloured or glaucescent; lacinie plane, 
sublinear, variously divided, with white farinose, scattered soredia 
(medulla K—). Apothecia subterminal, moderate, concave, pale or 
glaucous, the receptacle unequal beneath ; spores oblong, straight or 
slightly curved, 0,010-15 mm. long, 0,004-6 mm. thick.—Gray,

Related to R. farinacea as well as to the preceding species, but dis- 
tinguished from both by the laciniz and the soredia. The lacinie are 
variable, the typical form being that described (elation Ach. Lich, Univ. 
p. 608). The soredia are numerous, though occasionally they occur only 
towards the apices, sometimes rendering the thallus inflated on the oppo- 
site surface. In this country the apothecia are rarely met with. The 
spermogones, which are also rare, have the spermatia cylindrical, about 
0,004 mm. long, and 0,001 mm. thick. 
Hab. On the trunks and branches of old trees, rarely on rocks, in 
wooded maritime and upland tracts.—Distr. General and common in 8.
