Generally recognized by the presence of massed groups of dark- 
green coralloid cephalodia, which have been sometimes described as a 
separate plant, Dendriscocaulon bolacinwm (Nyl. in Flora lxviii. p. 299 
(1885) ; Cromb. Monogr. i. p. 77). It is one of our largest lichens and 
is of a rigid coriaceous texture; the somewhat imbricate lobes are 
elegantly crenate. Apothecia are rare; spermogones are more 
frequent, with spermatia about 5 » long and 1 p thick. 
Hab. On the trunks of old trees, chiefly ash and oak, rarely on 
rocks in maritime and inland districts.—Dzstr. Chiefly in the western 
tracts of Great Britain, rare in S.W. and N. Ireland and in the

wrinkled, often shining, green when moist, pale-brown when dry, 
the lobes somewhat laciniate, rounded, subcrenate and undulate, 
beneath covered with a pale tomentum, and with pale rhizinz 
(K —, CaCl—). Apothecia small or large, generally crowded 
towards the centre of the thallus, reddish, the margins rather 
granulate, inflexed; spores fusiform, 1-sepate, becoming pale-—
