Distinguished from the preceding, which it resembles in habit, by 
being much smaller (usually about 1-2 inches in height), more csespitose, 
branched and fibrillose. Occasionally it is very small and pulvinate, and 
is sometimes only sparingly sorediiferous, ‘The apothecia are very rare 
in Great Britain, and are found only on the smaller conditions. Minute 
cephalodia, however, are not unfrequent on the main branches. 
Hab. On old pales (oak and larch), and occasionally on the branches of 
trees in wooded tracts Distr. General in maritime and upland districts, 
sometimes abundant, especially in the Central Highlands of Scotland ; 
apparently rare in Ireland and in the Channel Islands.—B. M. : Island of
