In favourable situations this spreads extensively, though more fie- 

 quently it occurs in small, interrupted patches. Nearly agrees with 



C. chrysocephcihnn in the colour of the thcdlus, though the colour of the 

 apothecia and the spores are very diverse. Often infertile; when present 

 the apothecia are generally very numerous. 



Hah. On the trunks of old trees, chiefly oaks, in upland wooded dis- 

 tricts. — Distr. Pretty general and common in England, rare in Wales; 

 very rare in S. and Central Scotland and in X. and W. Ireland. — B. M. :

Form ] . viride Nyl. Syn. i. (1860) p. 153. — ThaUusthin, leprose or 

 grauulato-fjulvcrulent, greenish-yellow, the stipes occasionally very 

 short ; capitulum often greenish- or greyish-pulverulent, black 

 beneath. — Cromb. Grevillea, sv. p. 14. — Calicivm viride Pers. Ust. 

 Ann. vii. (1794) p. 20. 



This form is distinguished by the more pulverulent thallus and the 

 colour of the capitulum above, though this latter character is not always 

 present. The stipes is occasionally very short, so that the apothecia are 

 almost sphiuctriuiform (=form sessile Cromb.) — a condition which is 

 referred to by Turner and Borrer in Lich. Br. p. 14i'. 



Hah. On trunks i.f old trees and on pales in wooded upland situation.'^.
