Differs merely iu the suow-white colour of the podetia, which become 

 lirowiiish at the apices. The only British specimens seen are sterile. 



Hab. On mossy rocks iu maritime and upland tracts. — Distr. Very 

 local and scarce in N. England and the S.W. Hi^'hlands of Scotland. —

Except in the foliaceoiis podetia this form is also entirely similar to 

 the type. It appears to be very rarely fertile, the apothecia when present 

 being usually simple and dark-brown. 



Haf). On the ground in upland situations. — Di-^tr. Somewhat local,

 or Ireland. — B. M. : Shiere, Sun-ey: Lydd, Kent: Basingstoke, Hants;

This is a more robust and less-branched plant, having the podetia either 

 erect or prostrate, with the cortex rugoso-unequal, usually more or less 

 squamulose (form lepid<jta Del.), and occasionally variously difform. It 

 somewhat resembles states of subsp. C. racemosa, but it has with K the 

 reaction of C. pum/ens, of which it forms a well-marked subspecies. The 

 apothecia are extremely rare iu our British specimens. 



Hab. On the gi-ound in upland situations. — Distr. Local, though some- 

 what plentiful where it occurs, in S., Central, and W. England. — B. M. : 

 Shiere, Surrey : Basingstoke, Hants; near Amberley, Sussex; Thetford 

 Road, Gloucestershire; Bathamptou Downs, Somersetshire ; Charnwood
