 more recent authors. Brit. Exs. : Mudd, Clad. nos. 46, 47 ; Leight. 

 n. 401 ; 13ohl, n. 23. 



The more or less (sometimes sparingly) fissured podetia and the form 

 of their apices characterize this variety. The podetia, which are fre- 

 quently sub.<padiceous, vary in length from 1 to 5 in., and in our British 

 specimens are, usually somewhat slender and rarely sparingly foliiferous. 

 With K the reaction, at least in paler specimens, is often slightly yellow, 

 quickly turning to brownish. It is usually well fertile, the apothecia 

 being numerous on the subcorymbose apices. 



Hob. On the ground and on turf-walls iu wooded upland districts. 

 Distr. Somewhat local and scarce in England, N. Wales, S. Scotland, 

 and S. Ireland ; more frequent, however, among the Scottish Grampians.

This differs in the rather lax, irregularly branched and curved podetia, 

 bearing scattered, short, erect or recurved spinules. The podetia, which, 

 though rigid, are brittle, are often subspadiceous, but when paler in 

 colour they usually give with K a distinct yellow reaction. It is rather 

 rare in fruit, the apothecia being either simple or sparingly aggregate.

 districts. Distr. Probably general and common throughout Great Britain
